Hit any file-size limit exactly
Upload forms often reject images above a set size: 30 KB for a signature, 100 KB for a photo, 500 KB for a document scan. Instead of guessing with quality sliders, enter the limit in KB and this tool finds the best quality that fits.
We lower JPG quality first, because that keeps the full resolution. Only if the image still doesn't fit do we reduce its dimensions, and we tell you the new size in pixels. The result is always at or under your limit; if a target is impossible, you get a clear message instead of a broken file.
- Any target from 5 KB to 5,000 KB
- Keeps full resolution whenever quality reduction is enough
- Output is always at or under your limit
- Transparent PNGs are placed on a white background
- Location and camera metadata removed
