Will a scanned receipt still be readable at 500 KB?

A single-page 300 DPI scan of a receipt compresses to about 200–400 KB and stays perfectly readable. A 10-page scan at 500 KB will look blurry and may be rejected by accounting software.

Does hitting 500 KB require removing images entirely?

No, but images are heavily compressed. Color photos may shift in tone or show blocky artifacts. If image fidelity matters, use the 1 MB target instead.

Why is the 500 KB option slower than the standard compressor?

The tool runs multiple passes, testing different image quality levels until it finds the highest quality that still fits under 500 KB. That iterative process takes more time than a single-pass compression.

Can I compress a PDF to 500 KB for a government upload portal?

Yes, but test the result first. Some portals reject files that are 501 KB or larger, so aim a little under 500 KB if the limit is strict.

Reality check

Target sizes are best-effort. Scanned PDFs usually compress more; already optimized text PDFs may shrink only a little. Always verify file size and readability before upload.
