ImageToolShack started as a single focused collection of image tools. It's grown a bit since then. Between the image tools here, a dedicated PDF toolkit, a video processing suite, a full set of SEO audit tools, and one of the more comprehensive developer utility collections on the web, there are now well over 175 free tools spread across five sites — every one of them running in your browser, with no account required and nothing stored on a server.

This post is a tour of all five. If you came here for image tools and didn't know the others existed, there's a good chance at least one of them has something you've been using a paid or clunky tool for. All free, all instant, all private.

ImageToolShack — 32 Image Tools

You're already here, so the image tools probably don't need a full introduction, but the collection has grown since the blog was last updated and a few of the newer additions are worth calling out specifically.

The core tools — Image Compressor, Bulk Compressor, Image Resizer, Background Remover, WebP Converter, and EXIF Viewer & Remover — are all covered in detail elsewhere in this blog. But the expanded collection now includes some tools that go well beyond the basics:

Image Filters applies photographic effects — vintage, black and white, cinematic color grades, and more — directly in the browser. No Lightroom subscription needed for basic filtering work.

Sharpen & Blur gives you precise control over image sharpness and blur radius, which is useful for everything from softening a background to rescuing a slightly soft photo before it goes on a product page.

Pixelate & Censor handles the increasingly common need to redact sensitive information from screenshots, obscure faces, or blur out license plates and addresses before sharing images publicly. It's the kind of tool most people cobble together a workaround for — a dedicated tool that takes ten seconds is better.

Palette Extractor analyzes any image and pulls out its dominant color palette — useful for matching brand colors to photography, building color schemes from reference images, or understanding the color language of a visual style you want to replicate.

Animated GIF Maker and Slideshow Creator both handle multi-image sequences — great for product demos, simple animations, and presentation assets without needing dedicated software.

Passport & Visa Photo formats a photo to the precise dimensions and background requirements for US passports, UK passports, EU biometric documents, and a range of visa photo standards. If you've ever paid $15 at a pharmacy for a passport photo, this tool does the same job in your browser for free.

PDFToolShack — 28 PDF Tools

PDF is the file format that seems simple until you need to do anything with it beyond reading. Splitting a PDF, extracting specific pages, removing a password, converting to Word, adding page numbers, running OCR on a scanned document — each of these used to require either Adobe Acrobat (expensive), a desktop application (often sketchy freeware), or a website that uploads your documents to a server somewhere and does who-knows-what with them.

PDFToolShack handles all of it, entirely in your browser — no uploads, no server contact, your documents never leave your device.

The organizing tools are the most immediately useful for most people:

Merge PDF combines multiple PDF files into one, with drag-to-reorder before merging. If you've ever assembled a multi-document submission by printing everything and scanning it back in, this is what you actually needed.

Split PDF breaks a PDF into individual pages or custom ranges — useful when you receive a combined document and need only specific sections.

Compress PDF reduces file size for email — a scanned document that comes out at 15 MB from the scanner can typically be compressed to 1–2 MB with no visible quality difference.

Protect PDF and Unlock PDF add and remove password protection — the unlock tool works on PDFs you own but have lost the password to, or where a password was set unnecessarily.

PDF OCR extracts text from scanned documents using Tesseract OCR with support for 14 languages — turning a photographed or scanned page into searchable, copyable text. This is genuinely useful for anyone who regularly works with scanned contracts, receipts, or archival documents.

Watermark PDF stamps text or image watermarks onto PDF pages — useful for marking drafts, proofs, or confidential documents before distribution.

The conversion tools — PDF to Word, PDF to Excel, Word to PDF — are server-side (Phase 2) since those conversions genuinely require processing power beyond what a browser can handle, but the browser-based tools cover the vast majority of everyday PDF tasks. Full tool list at pdftoolshack.com.

VideoToolShack — Video Processing Tools

Video has become the default format for content, communication, and documentation — but working with video files has traditionally meant either expensive software (Premiere Pro, Final Cut) or uploading your footage to cloud services that process it on their servers. VideoToolShack brings browser-based video processing to the same model as the rest of the network: your files stay on your device, everything runs locally, no account required.

The core tools handle the most common video tasks:

Video Compressor reduces file size for sharing, uploading, or storage — particularly useful when you need to email a video or upload to a platform with a file size limit without sacrificing noticeable quality.

Video Trimmer cuts video to a specific start and end point — the most common video edit, handled entirely in the browser without re-encoding the full file.

Video Converter changes video format between MP4, WebM, MOV, AVI, and other common formats — useful when a file won't play on a particular device or platform, or when you need a specific format for a workflow.

Extract Audio pulls the audio track from any video file as an MP3 or WAV — handy for grabbing a soundtrack, creating a podcast clip from a video recording, or separating audio for further editing.

Video to GIF converts a short video clip into an animated GIF — useful for creating shareable reaction clips, product demos, or visual documentation that plays inline without requiring a video player.

TopWebPositions — 16 SEO Tools

If you run a website — any website, on any platform — your search rankings depend on a set of technical and on-page factors that are invisible to casual inspection but immediately readable by tools that know where to look. TopWebPositions provides 16 free SEO audit tools that cover the full range of what Google and other search engines evaluate.

The on-page tools are particularly useful for anyone who creates or manages web content:

Meta Tag Analyzer inspects any URL's title tag, meta description, canonical tag, and robots directives — with a live SERP snippet preview showing exactly how the page will appear in Google search results. If you've ever wondered why your carefully written title gets truncated in search, or whether your canonical is set correctly, this shows you instantly.

Open Graph Preview renders exactly how your URL's link card will appear when shared on Facebook, LinkedIn, X, Discord, and Slack. The number of websites with broken or missing OG tags — meaning their shared links show as plain text with no image — is remarkable. This tool catches those issues before they cost you social traffic.

Schema & Structured Data Tester validates JSON-LD schema markup — the structured data that enables rich results in Google Search (star ratings, FAQ dropdowns, recipe cards, breadcrumbs). Getting structured data right is increasingly important for search visibility, and this tool shows you exactly what Google sees and whether it meets the requirements for rich results.

SERP Snippet Counter measures your title and meta description in both characters and rendered pixels for desktop and mobile — because Google truncates based on pixel width, not character count, which means a 60-character title in a wide font can still get cut off. This is the tool that tells you definitively whether your title fits.

The technical tools handle the infrastructure-level factors that silently hurt rankings:

Redirect & Header Checker traces the full redirect chain for any URL — showing every hop, identifying redirect loops, mixed 301/302 chains, and SEO-critical response headers. A chain of three redirects costs you crawl budget and passes diluted link equity; this tool makes those chains visible.

Broken Link Checker finds dead internal and external links on any page — with the HTTP status code for each. Broken links hurt both user experience and crawlability, and they accumulate quietly over time as external sites restructure.

Robots.txt Tester parses any site's robots.txt and tests specific paths against any crawler — crucial for catching accidental deindexing, which happens more often than you'd expect, particularly after site migrations.

DevToolShack — 79 Developer Tools

This is the largest of the four collections by a considerable margin — 79 tools spanning text processing, HTML and CSS utilities, JavaScript and JSON, encoding and hashing, date/time tools, color tools, regex testing, network utilities, and more. DevToolShack is aimed squarely at developers, but a surprising number of the tools are useful to anyone who works with code, content, or data in any capacity.

A few that stand out across the categories:

JSON Formatter pretty-prints or minifies JSON, validates structure, and highlights errors. If you've ever received a wall of unformatted JSON from an API and tried to read it, this is the tool that makes it human-readable in one paste.

Regex Tester tests regular expressions against sample text with live match highlighting — the standard tool for anyone writing or debugging regex patterns without having to run code to test them.

JWT Decoder decodes JSON Web Tokens to inspect headers and payloads without verification — useful during API development and debugging when you need to see what's actually in a token.

CSS Specificity Calculator calculates the specificity of any CSS selector — the tool that ends the guesswork when a style isn't applying and you can't figure out which rule is winning.

Color Contrast Checker validates foreground/background color combinations against WCAG accessibility standards — essential for anyone building accessible web interfaces, and increasingly a legal requirement for many types of websites.

Cron Expression Builder builds and validates cron job expressions with a visual interface — because the cron syntax is just unintuitive enough that even experienced developers look it up every single time.

Text Diff Checker shows a highlighted character-level diff between two text blocks — useful for comparing versions of content, config files, API responses, or anything else where you need to see exactly what changed.

Unix Timestamp Converter converts between Unix timestamps and human-readable dates in any timezone — the perpetual lookup that every developer does dozens of times a week, now bookmarkable.

The Common Thread

All five sites share the same design philosophy: tools that do one job well, run entirely in your browser, require no account, and keep your data on your device. It's a deliberate reaction to the standard model of web-based tools — upload your file to our servers, create an account, get five free uses per month, pay for more.

That model made sense when computation had to happen on a server. Modern browsers are powerful enough to handle image processing, PDF manipulation, video conversion, code formatting, and cryptographic operations locally — which means there's no longer a technical reason to route your files through a third party. The privacy benefit is real, the speed is better (no upload/download round trips), and there are no account walls to run into at inconvenient moments.

Between the five sites, the toolset covers a meaningful portion of what web workers, content creators, photographers, developers, and small business owners reach for on a daily basis — without any of the friction that usually comes with it. They're free, they'll stay free, and they work on any device with a modern browser.
