Compress image to 50KB
Aim for a 50KB file and inspect fine lines before saving. Signatures and text need a visual check as well as a smaller byte count.

How the 50 KB compression search works
The initial 50KB target is 51,200 bytes. The tool searches JPEG quality, then tries smaller dimensions if allowed and still necessary. A decodable source already at or below the target is returned unchanged. Otherwise, compare the re-encoded result with the original before downloading.
Where compressing an image to 50 KB falls short
- Re-encoding produces JPEG and fills transparency with white. An unchanged source keeps its format and transparency.
- Fine text or strokes can lose clarity, and some sources cannot meet the selected ceiling. Neither outcome is judged automatically.
Questions about compressing an image to 50 KB
Is 50KB enough for a scanned signature?
Check the actual result. There is no universal quality threshold for a signature: stroke thickness, source dimensions and background detail all affect the output.
What happens if I add a file that is already 30KB?
If the browser can decode it and it is at or below the target, the tool returns its original bytes, including the format and metadata.
Why did my transparent PNG become white?
An image that needs re-encoding is drawn on white and saved as JPEG. A PNG that already meets the limit is returned unchanged instead.
Can I use 40KB rather than 50KB?
Yes. Enter a custom target from 1 to 10,240KB and run the tool again. Confirm the current field value and achieved byte count before saving.
