How to compress to an exact file size
Three steps.
Drop your photos in
One or many; each gets its own search.
Type your target
In the size-target box, enter the limit (say 500 KB), or pick a preset. The app tries quality levels and picks the best one that fits under your number.
Hit Squish
Files come out under the limit, not rounded to it, each checked against its original.
Under the number, not near it
Most tools that promise a target size get close and call it done, or hit the number and quietly wreck the quality. The honest version is a search: try quality levels, measure real file sizes, keep the best one that genuinely fits, and prove the picture still looks right.
That’s what happens here, per file. Upload forms, email limits, marketplace listings: type the number they gave you and the file arrives fitting it.
Good to know
- Targets in KB or MB, any value.
- Handy presets included: 120/240 KB, 500 KB, 1 MB, 5 MB, 12 MB, 16 MB, 20 MB, 25 MB.
- Every result is checked before saving.
Questions, answered
Can it hit an exact size, like exactly 500.0 KB?
It aims safely under your limit rather than at it, so nothing you upload gets rejected for being a few bytes over.
What if the target is impossible, like 50 KB for a huge photo?
You still get the closest result that fits, and the quality slider tells the story of the trade you made.
Is it really free?
Yes. It costs nothing, needs no account, and whole batches run one after another. Every input format and the full quality engine are included. If you point it at a really big collection you’ll eventually meet the free limit; Pro ($9 once) removes it and adds a watch folder, or you can simply come back tomorrow.
Does it overwrite my originals?
Never. Finished files are written under new names, so the originals and the results live side by side.
Type the limit. Get under it.
