PRIVACY FOR THIS JOB

Your document stays under your control

All 0.5 MB optimization attempts run inside browser memory. The original pages remain on the device.

LIMITS TO KNOW

Check these before you start

  • Photo-heavy or multi-page files may not reach 500 KB without unacceptable quality loss.
  • Searchable text is rasterized in target-size mode.
  • Check fine print and signatures at 100% zoom before submitting.

0.5 MB target

This preset allows more detail than 100 KB while still aiming at upload forms with a strict half-megabyte limit.

USE THIS WHEN

Good fit for this job

  • ✓ A short scanned application must fit a 500 KB form
  • ✓ The PDF contains a few pages with moderate detail
  • ✓ The destination shows an explicit 500 KB maximum
CHOOSE CAREFULLY

When to use another option

Use 1 MB for color scans or several pages of small text.

Use 100 KB only when the destination truly requires it and the document is very short.

BEFORE YOU SHARE

Check the downloaded result

  1. 1Compare the actual size with the destination's exact unit wording
  2. 2Inspect seals, dates, and identification numbers
  3. 3Confirm every page is present and correctly oriented
QUESTIONS FOR THIS JOB

Practical answers

Is 500 KB the same as 0.5 MB?

This tool uses 0.5 MiB as its browser target. Some portals use decimal units, so always compare the measured file size with the exact rule shown by the destination.

Will searchable text remain searchable?

Target-size compression may rasterize pages. Run OCR afterward if search and text selection are required.
