Tips
- Balanced keeps most detail while cutting size for mail and LMS uploads.
- Lower DPI and quality reduce images most; text stays vector for sharpness.
- Use grayscale when color is not essential to shrink scans further.
- Very large PDFs take longer. Watch the in-app progress and keep the tab open until it finishes.
- Text-heavy PDFs are often already small, so compression impact may be modest.
FAQ
What should I check before exporting a PDF?
Load the PDF, confirm the page range or output format, then export a small sample if the file is large. This keeps browser-only processing predictable.
Why might another PDF tool produce a different file?
PDF tools can choose different image settings, font handling, compression levels, or page box rules. Compare a preview page before using the output in a workflow.
Can I rely on the exported PDF?
Use the preview and a quick download check before sharing. Browser processing is useful for everyday edits, but sensitive or regulated documents should be reviewed in your normal document workflow.
Can I reproduce the same export later?
Yes if you keep the same source file and settings. Save the output with a clear filename so the page order, format, or compression choice is easy to verify.
Are my PDF files uploaded?
PDF processing runs in your browser. Files are not uploaded automatically; only use share or external storage when you choose to.
