Your files stay in your browser. Nothing is uploaded.
How to compress an image
- Drop your JPG, PNG or WebP files into the box above, or click to browse. You can add several at once.
- Pick a quality level with the slider. Around 80% keeps an image looking sharp while removing most of its weight.
- Each file is compressed instantly, on your device. Download them one by one, or grab everything in a single ZIP.
There is no queue to wait in and no email to hand over. The moment you drop a file, your browser does the work and hands the smaller image straight back to you.
Why compress images in your browser?
Most online compressors upload your photos to a server, shrink them there, and send them back. Edit·Tool doesn't. Your images are read and re-encoded entirely on your own device, using the image engine already built into your browser.
- Private by default. Nothing is uploaded, so nothing can be logged, stored or leaked. Your files stay on your computer or phone.
- Faster for big batches. With no upload and download round-trip, large sets of images finish in seconds.
- Free with no limits. No accounts, no watermarks, no daily caps.
Which formats can I compress?
Compression works on the three formats that make up almost all of the images on the web:
- JPEG (.jpg) — best for photographs. The quality slider trades a little fine detail for a much smaller file.
- PNG (.png) — lossless, ideal for logos, screenshots and graphics with sharp edges or transparency.
- WebP (.webp) — a modern format that is usually 25–35% smaller than JPEG at the same visual quality.
How much smaller will my image get?
It depends on the format and the quality you choose. For a typical photo, lowering JPEG quality to 80% often cuts the file size by 60–70% with no visible change. Push the slider lower for web thumbnails, or keep it high when you need print-ready detail. PNG files are lossless, so they shrink less — for big savings on graphics, converting to WebP usually helps more than compression on its own.

Frequently asked questions
- Is the image compressor really free?
- Yes. Edit·Tool is completely free, with no account, no watermark and no daily limits. You can compress as many images as you like.
- Are my images uploaded to a server?
- No. Every image is processed locally in your browser. Nothing is sent anywhere, so your files never leave your device and cannot be stored or seen by us.
- Will compressing reduce the quality of my image?
- JPEG and WebP use lossy compression, so very low quality settings can soften fine detail. At around 80% and above the difference is usually invisible. PNG compression is lossless and keeps every pixel.
- Can I compress several images at once?
- Yes. Drop in as many files as you want — they are compressed one after another on your device, and you can download them all together in a single ZIP.
- Is there a maximum file size?
- There is no fixed limit. Because everything runs on your device, the practical ceiling is your phone or computer's memory rather than a server quota.
- Which browsers work?
- Any modern browser works — Chrome, Safari, Firefox or Edge, on desktop or mobile. No app or extension is needed.
