Increase image size to 100KB

Bring a small document image toward a 100KB minimum and inspect its readability separately. The padding count explains any added non-image bytes.

Sample
A sample photograph, before and after raising it to 100 KB
27.4 KB
100.2 KB
Drag the divider. Left is the 27.4 KB original; right is what this page produces from it 100.2 KB. Both halves are shown reduced in size and delivered as WebP; the tool writes JPEG, which looks slightly softer at the same byte count. Drop your own file anywhere on this preview, or pick a sample nearby, to run it for real.

Mechanism

How reaching the 100KB scan floor works

The initial floor is 102,400 bytes. A smaller image goes through JPEG quality search, optional upscaling and comment padding if needed. A source already meeting the floor stays unchanged. The actual mix depends on the input; the tool reports padding instead of assuming that a larger scan contains more detail.

Limits

Where increasing a document to 100KB falls short

  • Neither padding nor upscaling captures letters missing from the source. If text is unreadable, obtain a clearer scan or photo before processing.
  • A result can exceed the floor, including a small padding-segment overhead. Check any separate maximum size.
  • This handles browser-decodable image files up to 40MB each, not a PDF document or an OCR text-extraction task.
Questions

Questions about meeting a 100KB document floor

Why does the result include padding?

The allowed encoding and scaling attempts left it below the selected floor. The reported padding fills the remaining byte shortfall without adding document detail.

Will scaling up recover tiny unreadable letters?

No. It can enlarge existing content, but cannot recapture missing strokes. Compare the source and result, and use a better scan if the text is unclear.

Can I use a PDF scan here?

No. This tool requires an image the browser can decode, such as an appropriate JPEG or PNG export. Each input is limited to 40MB.

Does the tool extract or assess my document text?

No. It processes image pixels locally and does not run OCR or judge readability. Inspect the result yourself before using it.
