Drop in any JPG, PNG or WebP and get it under 1MB automatically - entirely in your browser.
Set a target in KB and the tool automatically searches for the highest quality that still lands under that size - no manual slider guesswork.
If quality alone can't reach your target, dimensions are scaled down gradually until the file fits - keeping as much detail as possible.
Compression runs on your browser's own Canvas engine. Files are never sent to a server, so there's nothing to leak and no upload wait.
Drop in dozens of files, apply the same target size to all of them, and download every result together in a single ZIP.
Drag the before/after slider on any compressed file to inspect quality loss side-by-side before committing.
Compress as many files as you like - no watermark, no account, no catch.
Drag and drop JPG, PNG or WebP images, or click to browse from your device.
Type a size in KB, or tap a preset - the tool works out quality and dimensions for you.
Grab each file individually, or all at once as a ZIP - no sign-up required.
Many websites, forms and marketplaces cap uploads at a specific file size - 1MB is one of the most common limits. Instead of dragging a quality slider and re-compressing over and over, this tool automatically searches for the highest quality that still lands under 1MB.
Tip: if quality alone can't reach 1MB on a very large photo, the tool gradually reduces the image dimensions too, so you still end up under your limit.
imgxcolor's target-size compressor shrinks JPG, PNG and WebP files to under 1MB directly in your browser - no software, no uploads, no cost.
Just set your target to 1MB (or use the preset), drop in your files, and download results that are guaranteed to be as close to - and under - that size as possible.
The tool runs a binary search on JPG/WebP quality to find the highest setting that still produces a file under 1MB. If the source is a lossless PNG or an extremely detailed photo that can't reach the target through quality alone, dimensions are scaled down step by step until the size fits.
Many upload forms, ad platforms, and marketplaces reject files over a hard limit rather than accepting "close enough" quality. Targeting 1MB directly guarantees your file will be accepted the first time, instead of trial-and-error with a quality slider.
Every compression runs locally with JavaScript and the Canvas API. Your images are never uploaded, stored, or transmitted. There are no accounts, no sign-ups, and no usage limits.
It runs a fast search over JPG/WebP quality settings to find the highest one that still produces a file at or under 1MB. If quality alone isn't enough, it also reduces the image dimensions in small steps until the file fits.
Yes. PNG is lossless, so quality can't be tuned the way JPG or WebP can - in that case the tool reduces dimensions until the file lands under your target, or you can switch the output format to JPG/WebP for a much smaller result.
The tool always aims for the best-looking result under your target. If it has to shrink dimensions significantly to hit a very small target on a very detailed photo, the compressed file is still labelled "closest possible" so you know before downloading.
Yes. Drop in as many files as you like, they'll all be compressed to the same 1MB target, and you can download everything together as a ZIP.
No. Everything runs locally using your browser's Canvas engine, so nothing is ever uploaded and results appear instantly.
