How to compress an image to 1 MB
- Click the box above or drag your image onto it. JPG, PNG and WebP all work, and you can add several at once.
- The tool tests quality levels automatically and picks the highest one that keeps the file under 1 MB.
- If even low quality is too large, it scales the image down step by step until it fits.
- Check the final size and dimensions next to the file name, then click Download.
When you need an image under 1 MB
- Email attachments, so several photos fit under the 20–25 MB limit
- Upload forms with a 1 MB cap
- Printing at up to A4 size while keeping files manageable
Getting the best result at 1 MB
For most photos, 1 MB is enough to keep the original resolution and simply re-encode at a smarter quality level. Only very large camera files (24 MP and above) will need slight downscaling.
File size depends on detail, not just dimensions. A photo of a plain wall compresses to a fraction of the size of a photo of leaves or gravel at the same resolution. That is why the tool measures the real output rather than guessing from a formula — every image gets its own best setting.
How it works
JPG and WebP use lossy compression controlled by a quality setting from 0 to 100%. The tool runs a binary search: it encodes the image at 95%, then halves the range again and again until it finds the highest quality that fits your limit, which takes only a few tries. Reducing quality before dimensions keeps text and faces as sharp as possible. Everything happens with your browser's built-in image engine, so nothing is uploaded.

Frequently asked questions
How do I reduce an image to 1 MB?
Drop your image into the box above. The tool tries progressively lower quality settings until the file fits under 1 MB, and only reduces the pixel dimensions if quality alone is not enough. Then click Download.
Will my photo still look good at 1 MB?
The tool always keeps the highest quality that fits. At this size most photos look identical to the original on screen.
Is my image uploaded to a server?
No. All compression runs in your browser. Your image never leaves your device, which matters for ID photos and signatures.
Can I choose a different size?
Yes. Change the "Target size" box to any value in KB — the 1 MB preset is just a starting point.
Should I choose JPG or WebP?
Choose JPG for application forms and government portals, because some of them reject WebP. Choose WebP for websites: it looks sharper at the same file size.
