How to use Compress an Image
- 1. Upload the image to shrink. Drop in any image file you want to reduce in size. It decodes in the browser and is ready for re-encoding at your chosen settings.
- 2. Choose the output format and quality. Pick JPEG for photos or WebP for broader compression gains from Output format, then set Quality (%) lower for smaller files or higher to stay closer to the original look.
- 3. Download the compressed file. Save the result once the preview and reported percentage saved look right. The new file is usually noticeably smaller than the original with only mild visual difference.
When to use Compress an Image
Compress an Image re-encodes any picture as JPEG or WebP at a quality level you control, cutting its file size while reporting how much was saved. It targets the everyday problem of images being too large for an email, upload form or page budget.
- Attaching photos to an email. A mail server rejects an attachment because a batch of full-resolution photos pushed the message over its size limit. Compressing each one with WebP at a moderate quality gets them under the cap.
- Speeding up a portfolio site. A photography portfolio loads slowly on mobile because every image is uncompressed straight from the camera. Running each through at 70 to 80 percent quality trims load time without visible loss.
- Fitting a marketplace listing limit. An online marketplace caps product photo uploads at a fixed file size, and a seller's photos come in over that limit. Compressing them here brings each file back under the threshold.
Examples

About the Compress an Image tool
Compress an Image does its work locally, right in the browser. Re-encode any image as JPEG or WebP to cut its file size. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Image Tools collection on EditSafely, a set of 200 small, focused Image utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Output format and Quality (%), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Compress an Image free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Are my files uploaded to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
Which files does Compress an Image accept?
It accepts images in any common format (PNG, JPG, WebP, GIF and more). There is no file size cap imposed by a server; very large files are limited only by your device's memory.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
