Compress PDF to 500 KB

Fit a multi-page scan under 500 KB with its text still readable

Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.

Five hundred kilobytes sits between the strict portals that stop at 100 KB and the relaxed ones that allow a whole megabyte, and it is where a five or six page scan usually lands without turning grey. The pictures inside the PDF are re-saved at lower resolutions, one step at a time, until the file fits; typed text and fonts are left exactly as they were. If no step reaches 500 KB, the smallest size achieved is reported rather than hidden.

How Compress PDF to 500 KB works

Compress PDF makes a PDF smaller by re-saving the photos and scanned pages inside it at a lower resolution and quality. You pick Smaller file, Balanced or Better quality, or type a target such as 200 KB, and you see the size before and after for every file along with the total saved.

People use it when an exam, bank or job portal rejects a scanned certificate for being too large, or when a report full of photos will not attach to an email. A ten-page phone scan of 12 MB often ends up around 2 to 5 MB on Balanced, which keeps the pages looking the same even zoomed in, or around 1 MB on Smaller file. A target-size run tries lighter settings step by step and keeps the best quality that fits; if nothing fits, it tells you the smallest size it reached.

How it works, and the trade-off: only pictures are re-encoded, as JPEG, capped at 100, 150 or 200 dots per inch of the page. Text, fonts, links and vector drawings are not touched, so words stay sharp, selectable and searchable, including the hidden text layer that scanner apps add. The cost is that a PDF made mostly of text barely shrinks, and images stored as black-and-white fax, JBIG2, CMYK or palette data are left as they are. If the result is not smaller, you get your original back, never a bigger file.

Frequently asked questions

How do I reduce the size of a PDF?

Drop the PDF on this page, pick Balanced (or Smaller file if it must be tiny), and click Compress. The photos and scans inside are re-saved at a lower resolution, and you see the size before and after. Download the smaller copy with one click. No signup and no upload.

How do I compress a PDF to 100 KB or 200 KB?

Choose Target size and type 100 or 200, or open the Compress PDF to 100 KB page. The tool tries lighter settings one after another and keeps the best quality that fits. A one or two page scan usually fits; if a long file cannot, it tells you the smallest size it reached.

Will the text in my PDF still be selectable after compressing?

Yes. Only pictures are re-encoded. Typed text, fonts, links and drawings are left exactly as they were, so you can still select, search and copy words, including the invisible text layer that scanner apps add to scanned pages.
