About Compress image to 1 MB
1 MB is a common upload limit on job sites, rental portals, and support forms. Most phone photos only need light compression to fit.
The compressor above is already in Target file size mode at 1000 KB. It binary-searches JPEG/WebP quality to land just under the limit and, if even low quality is too big, scales the image down step by step. It aims under 1,000,000 bytes so it passes forms that count 1 KB as either 1,000 or 1,024 bytes.
If the target cannot be reached (for example with PNG, which has no quality setting), the tool says so and shows the smallest result instead of pretending.
Rule of thumb: photo dimensions that usually fit in 1 MB
| JPEG quality | ≈ Pixels | ≈ Size at 4:3 |
|---|---|---|
| High (≈90%) | 2.9 MP | 1950 × 1460 px |
| Medium (≈75%) | 5.6 MP | 2720 × 2040 px |
| Low (≈50%) | 10.0 MP | 3650 × 2740 px |
Estimates for a typical photo. Detailed scenes (foliage, noise) need fewer pixels; flat graphics and documents fit more. The tool measures real file sizes, so trust its result over this table.
How to do it
- 1
Drop one or more images (JPG, PNG, or WebP).
- 2
Keep Target file size at 1000 KB, or type a different limit. JPG reaches small targets most easily.
- 3
Check the preview and the result line, then download (several files come as a ZIP).
