Is my PDF uploaded to crop it?

No. Cropping runs in your browser — the file never leaves your device. You can confirm it in your browser's network tab.

Cropping is a Pro feature. Reordering, rotating, splitting, merging and deleting pages are free — you can do all of those on this page — and Pro adds precise page cropping.

What does cropping do to the cropped-off content?

AttachKit crops each page to the area you choose and exports a trimmed PDF, so the result shows only the area you kept.

Crop PDF pages

Drop a PDF and crop the margins or whitespace off your pages, then download. You can also merge, split, rotate, reorder, and delete pages here. Everything stays in your browser; nothing is uploaded.

Merge: drop 2+ files → one PDF in page order
Split: one PDF in → many PDFs out (one per page, zipped)
Extract: select pages → one new PDF with just those
Reorder / rotate / delete: drag, then bulk-edit any selection
Compress: optional rasterize-to-JPEG (lossy)
Images → PDF: drop PNG / JPG, each becomes one page

Drop PDFs or images here

One file or many — they'll merge into a single grid you can reorder, rotate, delete, or split.

Crop PDF pages in your browser

Trim the margins or whitespace off your PDF's pages, then download — the file never leaves your device.

Nothing is uploaded

The whole thing runs in your browser — open your network tab and watch: your file never leaves your device. Most online tools round-trip your document through their servers.

Trim margins and whitespace

Crop the page to the area you want, cutting off excess margins or scanned borders, and export the trimmed PDF.

Plus every other page tool

Reorder, rotate, split, merge and delete pages in the same workspace — all in your browser.
