Sort, Reorder Pages & Organize Your PDF in Seconds

Yes. You can remove pages individually by clicking the delete control on each thumbnail, and you can work through the grid quickly since every deletion is instant and doesn't require a confirmation dialog. The visual grid updates in real time so you can verify exactly which pages remain before you download the final file. For large documents with many blank or duplicate separator sheets, this makes batch cleanup straightforward — scroll through the thumbnails, tap delete on every page you don't need, and the remaining pages automatically close the gaps.

Open the file in PDFBold and look for pages whose thumbnails appear rotated 180°. Click the rotation control on each affected thumbnail to turn the page in 90-degree steps until the orientation is correct. This is one of the most common scanner errors — a batch-fed document where half the sheets were loaded face-up and the other half face-down. Because every rotation is visible instantly on the thumbnail, you can fix mixed-orientation scans in seconds without re-scanning a single sheet.

You can open PDFs up to 60 MB. PDFBold does not impose an artificial page-count cap: long documents are limited mainly by your device RAM and CPU. A modern laptop or desktop can usually handle hundreds of pages; very large page counts (for example 1,000+ pages with heavy images) may render thumbnails more slowly. No data is sent to a server, so there are no upload timeouts or remote queues.

Yes. While there isn't a dedicated 'reverse' button, reversing page order is fast with the drag-and-drop grid. For shorter documents, simply drag the last page to the first position and continue until the sequence is flipped. For longer files, a practical workflow is to combine this tool with the PDFBold Split and Merge tools: split the document into individual pages, reassemble them in reverse using the merge tool's ordering controls, and then use this page to make any final adjustments.

No. Every thumbnail is rendered on the fly inside your browser's memory using your device's own hardware. The images are never written to disk, never cached on a server, and never included in any analytics or logging. The moment you close the browser tab — or even navigate away from the page — all rendered thumbnail data is released from memory and permanently destroyed. This applies equally to the original PDF data: nothing is retained once the session ends.
