Question 1

How do I reduce a PDF file size online for free?

Accepted Answer

Upload your PDF to PdfEditly's Compress tool, select a compression level — Low, Medium, or High — and click Compress. Your smaller PDF downloads directly to your device. The entire process runs in your browser with no uploads, no account, and no cost.

Question 2

What is the difference between Low, Medium, and High compression?

Accepted Answer

Low compression gives a modest size reduction with near-perfect quality — best for documents you'll print or present. Medium offers a balanced trade-off and works for most files. High delivers maximum shrinkage but may visibly reduce image quality. Choose based on the file's intended use.

Question 3

How much will compression reduce my PDF's file size?

Accepted Answer

Results vary depending on your PDF's content. Image-heavy or scanned PDFs typically shrink by 50–80% on Medium or High settings. Text-only PDFs may see smaller reductions since there are fewer images to compress. Preview the file before sharing to confirm quality.

Question 4

Will compressing a PDF damage the text or fonts?

Accepted Answer

No. Compression targets embedded images, not text or fonts. Text content, hyperlinks, and vector graphics in your PDF are not affected by any compression level. Only the resolution of raster images is reduced, which is invisible in most document viewing scenarios.

Question 5

Can I compress a scanned PDF?

Accepted Answer

Yes. Scanned PDFs are typically image-heavy, making them ideal candidates for compression. PdfEditly's Compress tool handles scanned files effectively, often achieving large reductions in file size. For scanned documents, Medium or High compression usually produces the best balance of size and readability.

Question 6

Is it safe to compress confidential PDFs online?

Accepted Answer

Yes — your file is never uploaded. PdfEditly compresses PDFs entirely in your browser using your device's processing power. No data is sent to any server at any point. This makes it completely safe for compressing confidential, financial, legal, or medical documents.
