Size-first

Get it under a size

Upload limits don't care about quality settings — they care about a number. Pick the number, and your browser finds the best-looking file that fits.

How the size search works

Three steps, all of them local to your machine.

1. Read

Your file is decoded in the browser from its real bytes, not its name.

2. Search

Quality is stepped up and down until the best-looking version that fits is found.

3. Report

You get the final size, the dimensions and the quality it landed on — no guessing.

Questions

How does 'get it under a size' actually work?+

Your browser re-encodes the image again and again at different quality levels, narrowing in on the highest quality that still fits under the number you picked. Nothing is uploaded while it searches.

What if my image can't reach the target?+

You'll be told exactly that, with the size it managed and the dimensions it used. Turning on resizing, or converting to WEBP or AVIF, almost always closes the gap.

Why do lossless formats like PNG barely shrink?+

PNG, BMP and ICO store every pixel exactly, so quality can't be traded away. Only smaller dimensions — or a different format — reduce the file meaningfully.

Will the target ruin my image quality?+

Only if the target is very aggressive. The search always keeps the best quality that fits, and you can see the final quality value next to every result.

Can I do a whole batch at one target?+

Yes. Drop as many images as you like, run them together, and download everything as one ZIP.
