Frequently Asked Questions

Everything happens in your browser. Nothing is uploaded.

Quick answers. If you still need help, contact support.

General

Do my files ever leave my computer?▼

No. All processing happens locally in your browser via canvas/WebAssembly. We never upload, store, or see your documents.

Is this free?▼

Yes. Optional ads (only if you consent) help keep LocalPDF free. You can use all features without ads.

Features

Organize▼

Reorder pages by dragging tiles. Rotate pages with the arrow buttons, then export.

Split▼

Click tiles to toggle which pages to keep. Export creates a PDF with just those pages.

Compress▼

Rasterize pages with adjustable DPI and JPEG quality. Try 110–150 DPI at ~80% for sharp text + smaller size.

Watermark▼

Add a diagonal text watermark. We measure the text and auto-fit it to the page so it doesn’t clip.

Convert▼

Export pages as PNG images (ZIP), or combine images to generate a new PDF.

Privacy & Ads

Why ask for consent?▼

To stay compliant and respectful. Ads may use cookies; without consent, we do not load ad scripts.

What cookies are used?▼

Only if you enable ads: Google AdSense may set advertising cookies. We also store a single localStorage key to remember your choice.

How do I change my choice?▼

Clear the “marketing-consent” key in localStorage or use the cookie bar again to switch.

Troubleshooting

“Failed to load PDF”▼

Ensure the file ends with .pdf. Some PDFs are encrypted/malformed—re-save them in a PDF editor and try again.

Thumbnails not rendering▼

Try a hard refresh; some networks block CDNs. If it persists, contact support with your browser & OS.

Watermark looks small▼

Very long words auto-shrink to fit the diagonal. Use a shorter text or increase opacity for visibility.

Pro Tips

Best compression settings?▼

Start with 110 DPI and 78–82% JPEG quality. Increase DPI for detailed graphics; lower quality for smaller files.

Merging PDFs fast▼

Drop multiple PDFs at once; pages append. Use Organize to reorder before exporting.

Images → PDF quality▼

We preserve original pixel dimensions for crisp output.
