What if pages have different sizes?

The ratio set on the preview (first page) is applied to every page — differently-sized pages are cropped by that same ratio.

Is my file uploaded to a server?

No. All processing happens inside your browser.

How do I trim just the margins?

Drag the selection to the content edges on the preview — the margins are removed on every page at once.

Can I crop pages differently?

The same ratio applies to all pages. For different crops per page, split the document first and crop each part.

How cropping works

Item	Details
Area selection	Drag on the preview to set the area to keep; fine-tune with corner handles
Scope	The same proportions are applied to every page of the document
Original kept	Content outside the area is hidden; the original file stays untouched

💡 Trimming margins and unwanted areas

Whether a scan has wide margins or captures parts you don't want, selecting just the area to keep makes a document look much cleaner.

✏️ Drag to select: Draw the area to keep on the preview, or fine-tune it with the corner handles.
📐 Applies to every page: The ratio you set is applied identically to all pages, even ones with different sizes.
🔒 Browser-only processing: Files are never sent to a server — processing happens only in your browser.

📌 Where is cropping a PDF useful?

Trimming scan margins — cut away the extra white space a scanner leaves around the page.
Matching a social/thumbnail ratio — crop pages to 1:1, 16:9 or another ratio you need.
Keeping only part of a page — extract just a table or figure and drop the rest.
Matching print trim lines — adjust margins to spec before sending to a printer.

✨ How to crop the exact area you want

Drag over the preview to mark the area to keep, then fine-tune it with the corner handles.
The ratio you set on the first page is applied to every page the same way.
Pages of different sizes are still cropped to match that same ratio.

🔒 Is the cropped-out area gone for good?

Yes. Cropping permanently removes everything outside the selected area when it saves. If you want to keep the original, make a copy of the file before cropping.
