Drop in a JPG, PNG or WebP file, pick a quality level, and watch the file size drop in real time before you download.
Drag a photo onto the box above, or click it to browse your device.
Lower the quality slider to shrink the file further, or switch to WebP for the smallest result.
The compressed file downloads straight to your device — nothing is uploaded anywhere.
Most free compressors work by accepting your upload, running it through a server-side process, then handing back a download link. That's an extra round trip, and it means a copy of your photo — even a private one — passes through infrastructure you don't control. Pixformet's compressor runs the same JPEG/WebP/PNG re-encoding logic your browser already supports, entirely on your device, so there's no upload wait and nothing stored anywhere but your own downloads folder.
Quality loss from compression comes almost entirely from the quality setting, not from where the processing happens — a well-tuned 80% JPEG looks identical to the original in almost every practical case, while cutting file size by half or more. That's exactly why the live before/after preview matters: you can see the trade-off before committing, rather than guessing and re-uploading if it looks wrong.
Common uses: shrinking product photos before adding them to a store listing, getting a blog's hero image under the size that hurts page-load speed, or fitting a photo under an email attachment or form-upload limit. If you're also unsure whether JPG, PNG or WebP is the right output format for the job, our Convert Format tool and blog cover the differences in more depth. Need an exact pixel size rather than just a smaller file? Try Resize & Crop instead.
At high quality settings (70–90%), the difference is usually invisible to the eye while file size drops significantly. Very low settings will introduce visible artifacts, which is why you can preview the result before downloading.
JPG suits photos and gives the smallest files. PNG preserves transparency and sharp edges (logos, screenshots) but produces larger files. WebP often beats both for a similar visual quality.
The tool runs in your browser's memory, so very large images (over ~40MB) may be slow on older devices, but there's no server-side limit or upload cap.
No. The compression happens locally using your browser's built-in image engine — the file never leaves your device.
