How to compress an image to 1MB
- Select Choose files, or drop a JPG, PNG or WebP image on the box.
- The tool aims for under 1MB on its own. It tests up to eight quality levels and keeps the sharpest result that fits.
- If quality alone cannot reach 1MB, it shrinks the image in small steps until it does.
- Select Download. The result is named with
-compressedso your original stays untouched.
When you need 1MB
One megabyte is a common cap for email attachments in bulk, chat apps, CMS uploads and many web forms. Modern phone photos are 3 to 8 MB, so a gentle compression is enough, and the image still looks great.
What the tool does to your image
JPG and WebP files are re-saved at a lower quality, starting at 95 percent and going down to 40 percent if needed. PNG files cannot be compressed by quality alone, so they are saved as WebP, which keeps transparency and is usually much smaller. If an image is still too large at the lowest quality, its width and height are reduced by 15 percent at a time, and you can see the final pixel size in the result row.
The page shows the size before and after, so you can check that the file is under 1MB. Very small images that are already under 1MB are still re-saved at high quality, which is usually a little smaller.
Tips
- At 1 MB the quality loss is hard to see. Try your result at full zoom to check.
- HEIC photos from iPhones can be converted first with HEIC to JPG.
- Need something tighter? See compress to 200KB.
- For more control, use the full image compressor.
- To change dimensions first, try the image resizer.
