From to-do to done.
- Choose up to 10 static JPG, PNG or WebP images.
- Name up to three requirements with original, maximum or exact pixel dimensions, output format and a KB limit.
- Review measured results. Download passing images individually or together, with an exclusion report.
A few good questions
How do I compress an image to 200 KB?
Choose a photo and keep the default 200 KB JPEG requirement. Confirm a white background if the source may contain transparency, then prepare results. You can enter any whole-number limit from 10 to 20,000 KB.
Does it produce exactly 200 KB?
The file must be at or below your limit; we do not add padding bytes. Here 1 KB means 1,000 bytes, so 200 KB means 200,000 bytes. Every result shows its actual byte count.
Will it change my image dimensions?
Original dimensions are the default. Maximum bounds preserve proportions. Exact sizing requires your choice of padding or a centered crop. Enlargement is opt-in. The tool never secretly reduces pixels to meet the byte limit.
What if an image cannot meet a requirement?
The result explains the failed condition and is excluded from downloads. Adjust the explicit dimensions, file limit or format and retry from the original. A ZIP includes passing images and a CSV explaining excluded results. Matching your numbers cannot guarantee acceptance by another site.
Can I reuse settings?
Save a settings JSON file and load it on another visit. This includes only named requirements, never your photos. Source images and generated previews are held for the open workspace and cleared on reload.
What happens to transparency, metadata and animation?
JPEG needs a confirmed white background for possible transparency. PNG and WebP can preserve transparency. Re-encoding omits original metadata and may change colors; inspect the preview. Files already meeting every condition can be copied unchanged, retaining metadata. Animated PNG/WebP, GIF, HEIC, PDF and video are rejected.
