Compress images
Quality mode balances clarity and size. Target-KB mode searches within a quality floor and cannot guarantee every image will reach the requested size.

Size and quality comparison
Every result shows input size, output size, dimensions, and actual savings.
No target-size guarantee
If the quality floor is still too large, the smallest result is kept and marked as target not met.
Common uses
Compress to 50 KB or 100 KB
Aim for a form, ID-upload, or admin limit and verify whether the file really meets it.

Frequently asked questions
Are images uploaded to a Toop server?
The page does not call a Toop image-compression API. Selection, decoding, compression, and download generation happen in your current browser.
Will every image reach 50 KB?
No. The tool searches within an allowed quality range and clearly marks results that remain above target.
Why is PNG harder to compress to a target?
PNG is lossless, so browser quality settings do not reduce it like JPG or WebP. Resize it, or choose another format when transparency is not required.
Will dimensions change?
Not by default. Dimensions change proportionally only when you provide a smaller maximum dimension.
Why did the output not get smaller?
Some files are already optimized. If re-encoding is larger and dimensions are unchanged, the smaller original is retained and labeled.
