IMAGE COMPRESSOR
Shrink JPG, PNG & WebP files without visible quality loss · Everything happens in your browser · No upload, no signup, no data stored
How to Use the Image Compressor
- Drop one or more images (JPG, PNG, or WebP) into the upload box, or click it to browse your files.
- The tool compresses them immediately with sensible defaults — WebP output at 82% quality, which looks identical to the original for most photos.
- Adjust the quality slider or switch the output format if you want a different balance of size and fidelity; results update live.
- Optionally set a maximum dimension — if a photo is 4000 pixels wide but will only ever be viewed small, resizing it is the single biggest saving available.
- Compare the original and compressed versions with the preview toggle, then save images individually or hit Download All.
About This Tool
Image files are usually far larger than they need to be. A phone camera saves photos at maximum quality and resolution because it assumes you might print them poster-sized — but for sharing in a chat, attaching to an email, or putting on a website, most of that data is wasted. Compression removes the excess: converting to an efficient modern format like WebP, encoding at a visually sensible quality, and optionally scaling oversized dimensions down.
The phrase worth knowing is "visually lossless." Modern encoders are good enough that at around 80–85% quality, the compressed image is mathematically different from the original but indistinguishable to the human eye — while being anywhere from 60% to 90% smaller. That is the default this tool starts from, and the before/after preview lets you verify with your own eyes rather than taking our word for it.
There is also a privacy bonus most people never think about: photos taken on a phone carry hidden EXIF metadata — the exact GPS coordinates where the photo was taken, the date and time, and the device model. Because this tool re-encodes the pixel data from scratch, all of that metadata is stripped from the output automatically. And unlike most online compressors, nothing is uploaded: every image is processed inside your own browser.
Frequently Asked Questions
Does compressing an image reduce its quality?
Technically yes, but at reasonable settings the difference is invisible. Lossy formats like WebP and JPEG discard information the human eye barely perceives. At this tool’s default of 82% quality, most photos are 60–80% smaller with no visible change — use the Original/Compressed preview toggle to check for yourself.
Should I choose WebP, JPEG, or PNG?
WebP produces the smallest files at the same visual quality and is supported by every modern browser, so it is the best default for web use. Choose JPEG when you need maximum compatibility with older software or upload forms. Choose PNG only for graphics that must stay pixel-perfect — logos, screenshots, images with text — because it is lossless and much larger for photographs.
Are my images uploaded to your server?
No. The entire compression happens in your browser using its built-in Canvas engine. Your images never leave your device, we never see them, and nothing is stored — close the tab and every trace is gone.
Why did my image get bigger instead of smaller?
It was probably already heavily optimized, or you converted a small efficient JPEG to PNG, which is a larger format for photos. The tool shows a red badge when this happens. Try WebP output, a lower quality setting, or a smaller maximum dimension.
Does the tool remove location data from my photos?
Yes. Re-encoding rebuilds the image from raw pixels, which discards all EXIF metadata — including GPS location, capture time, and camera details. The compressed file you download contains only the picture itself.
