Get images under 1 MB for email and uploads
Many upload forms, email services and school or job sites stop at 1 MB per file. Choose 1 MB and every photo is saved just under it at the highest JPG quality that fits, usually at full resolution, so it still prints and zooms well.
This is the gentlest of the exact sizes: most photos only lose detail you would need a magnifier to spot. Add up to 30 images or 200 MB at a time and download them together as a ZIP.
Frequently asked questions
Add it here, keep 1 MB selected and click Compress images. The downloaded JPG is under 1 MB, counted as 1,000,000 bytes so it passes any limit.
Usually yes. At 1 MB a typical phone photo keeps its full pixel size, which is enough for a sharp print up to about A4.
Yes. Several photos under 1 MB each fit comfortably within most email attachment limits.
JPG and WEBP compression is lossy, but Recommended keeps a balance that suits most photos, and Smallest that looks the same checks each result against the original. PNG and SVG compression is lossless, so nothing visible changes in those files.
Up to 30 images or 200 MB per task. Add them all, click Compress once, and download the results one by one or together in a single ZIP file.
Some files are already well optimized. When the compressed version would be the same size or bigger, you get your original file back unchanged, and it is marked as already optimized.
No. Compression runs inside your browser on your own device. Your images are not uploaded or stored anywhere, which also means a large batch never waits for an upload to finish.
Recommended is fast and works well for most images. Choose Smallest that looks the same when file size matters most. It is slower, and a very detailed photo can sometimes come out larger than with Recommended.
