Image tools thatrespect you
imgmod is a focused suite of fast, free image tools. Every one runs entirely in your browser — no uploads, no accounts, no watermarks, no limits. This is who we are and why the site exists.
The web is full of image tools that ask you to upload a personal photo to a stranger's server, wait in a queue, and download a watermarked result. imgmod exists because that model is slow, it is invasive, and in 2026 it is also unnecessary — modern browsers can do all of this work locally, instantly, and for free.
The mission
Give people a complete set of everyday image tools thatnever see their files. Converting a HEIC from an iPhone, shrinking a photo for an email, stripping GPS data before sharing, cropping for a profile picture — these are quick tasks, and they should stay between you and your device. No middleman should ever need a copy of your photo to help you resize it.
How the privacy actually works
Each tool is a single web page built from HTML, CSS and ordinary JavaScript. When you drop a file into one, the browser reads it with the File API and does the work on a<canvas>element or in typed arrays — entirely in memory, on your machine. The result is handed back to you as a download. There is no server-side processing step because there is no server processing.
This is not a claim that depends on trust. Open your browser's developer tools, go to theNetworktab, and run any tool. You will watch your image being processed without a single upload request leaving your device. The promise is verifiable.
What's inside
imgmod bundles eight core tools and dozens of focused pages for the conversions and sizes people actually search for:
- Convert— HEIC, WebP, PNG, JPG, AVIF and BMP to and from each other.
- Compress— JPG, PNG and WebP, with a live quality slider and PNG palette quantization.
- Resize— by exact pixels or percentage, aspect-ratio locked, batch ready.
- Merge— combine images side by side, stacked or in a grid.
- Clean— strip EXIF, GPS and camera metadata from photos.
- Crop— exact pixel presets for Instagram, Facebook, Twitter and more.
- Cut— auto-slice sprite sheets and export animation atlases.
- Zip— batch-compress a folder of images into one download.
The principles that don't move
| Principle | What it means here |
|---|---|
| Private by structure | Files are processed locally. Not a setting to toggle — it is how the tools are built. |
| Free, really free | No watermark, no sign-up, no usage cap, no hidden "Pro" tier that gates basic features. |
| Instant | No queue, no waiting room. The result appears the moment you act. |
| Everywhere | Any device with a modern browser — desktop, laptop, tablet or phone. |
| No lock-in | Nothing is stored server-side, so there is no account to delete and no data to export. |
Why "browser-based" is usually the right answer
For quick, everyday tasks, a web tool is faster than downloading, installing and learning dedicated image software. There is nothing to update, nothing taking up disk space, and nothing running in the background. The trade-off is that a browser tool will not match a professional desktop editor for heavy, repeated production work — and that is fine. imgmod is for the 90% of image jobs that take ten seconds.
Under the hood
The tools lean on a handful of well-established open-source libraries where the browser's built-in APIs are not enough: PNG palette quantization via UPNG, DEFLATE via pako, ZIP packaging via JSZip, HEIC decoding via heic2any. These are loaded lazily — for example, the PNG libraries are only fetched when a PNG actually needs compression — so most visits download almost nothing extra. Everything is static: no backend, no database, no build-time server logic.
