Compress Image to 1MB
Compress an image to under 1MB, free. Reduce the file size of a JPG, PNG or WebP picture or screenshot. It runs in your browser, so nothing is uploaded.
How it works
- Choose your image. It opens on your own device and is not sent anywhere.
- The tool finds the best JPG quality that stays under 1MB, and only shrinks the pixel size if quality alone is not enough.
- If your form asks for exact pixels or a minimum size, open "More options". The image is cropped from the centre to match the pixel size.
Tips for a 1MB limit
A limit this generous keeps the full pixel size of most pictures and is close to the original on screen. It suits scans, certificates and screenshots where fine detail matters.
What fits in 1MB
A rough guide to the largest pixel size an image can keep at 1MB. Plain backgrounds fit more pixels than busy ones. If yours is larger, the tool lowers the pixel size so it stays clean instead of turning blocky.
| Quality | Largest size |
|---|---|
| Sharp, holds up when zoomed in | 2160 × 1620 px |
| Clear, fine for most forms | 2640 × 1980 px |
| Acceptable when shown small | 3740 × 2810 px |
Reducing image size without losing what matters
Crop away anything you do not need before compressing. Screenshots and flat graphics shrink far more than photographs, so a photo may need a larger limit to stay sharp. PNG and WebP files are converted to JPG, which is what makes them smaller.
Questions
Is my file uploaded to a server?
No. All the work happens inside your browser. The file never leaves your phone or computer.
Why is my result much smaller than the limit?
The limit is a maximum. If the picture already looks its best below it, there is nothing to gain from a larger file.
What format is the result?
JPG (also written JPEG), which is what almost every application form accepts. PNG and WebP pictures are converted for you.
Will the image look blurry?
The tool keeps the highest quality that fits under your limit. A very small limit on a large, detailed picture will lose some sharpness.
Does it work on a phone?
Yes. It works in the browser on Android and iPhone, with nothing to install.
