Frequently asked questions
How does it reach an exact size?
FileDagadu searches for the highest JPG/WebP quality whose file size still fits under your target. If even the lowest quality is too big, it also reduces the image dimensions a little until it fits.
Why is my result a bit smaller than the target?
The goal is the largest file that is still under your limit, so the result is usually just below it (for example 48 KB for a 50 KB target). Sizes are measured with 1 KB = 1,024 bytes, the way most upload portals count.
Can I compress to a minimum size as well, like 20–50 KB?
This tool sets an upper limit. If a portal also needs a minimum, compress to the upper limit and check the result — most photos land close to the target.
Is my photo uploaded anywhere?
No. Everything happens in your browser, so your photo, signature or ID never leaves your device.
