JPG, PNG or WebP — batch supported
Uncheck to always output JPG (smallest).
Re-encoding can increase file size. Target mode preserves dimensions, with a minimum quality of 10%; an unreachable target is reported.
Example and output check
Choose a photo and a target in KB. The tool searches encoding quality at the original dimensions. If even 10% quality exceeds the target, it reports the limit instead of silently shrinking the photo.
Before you use the result
PNG compression has no JPEG-style quality slider. Re-encoding can make a file larger. Compare actual output bytes and retain the original if the result is not useful.

- 1 Drag your images into the box, or click to browse. Batch mode supported.

Frequently asked questions
Why can my target size fail?
The target may be below the smallest result possible at the current dimensions and minimum 10% quality. Resize first or increase the target.
Is a smaller image always better?
No. Lower quality can smear text or fine detail. Inspect the downloaded image at its intended display size.
