Start with lossless structural compression, then inspect the result at normal zoom and at 200%. Text should remain sharp, diagrams should keep legible labels, and photographs should not show distracting blocks or colour bands. Keep the original file until you have checked every page and confirmed the smaller copy still suits its destination.

To merge PDFs without uploading them, use a browser-based tool that processes files on your own device instead of a server. FeelPDF’s Merge PDF does exactly this: it combines your PDFs locally using WebAssembly, so the file bytes never leave your computer. It is free and needs no account.

Safe redaction removes the underlying information from the exported file. Drawing a black shape over text is only an annotation and may leave the words selectable, searchable or recoverable. Use a redaction workflow that flattens the affected area, then reopen the result and test selection, search, copying, metadata and hidden attachments before sharing it.

For private OCR, use an engine that runs on your device, choose the document language, and start with a straight, high-contrast scan. Review names, numbers, tables and unusual fonts against the page image rather than trusting the transcript blindly. OCR creates a best-effort interpretation, so preserve the original scan as the authoritative visual record.

Encrypt the PDF with a unique, long password, download the result, and test it in a separate viewer before sharing. Send the password through a different channel from the document. Encryption controls who can open the copy, but it cannot stop an authorized recipient from saving, photographing or forwarding content after they unlock it.

Split the document at logical boundaries rather than at an arbitrary file size, then name each part with its sequence and page range. Verify the first and last page of every output and include a short contents note in the message. Splitting preserves page quality; compression can be tried separately if a single attachment is essential.

Draw your signature locally, place it on the correct page, export the signed copy and reopen that copy to verify its position and legibility. A drawn electronic signature records your visible intent but is not the same as a certificate-backed digital signature. Confirm what the receiving organization accepts before signing an important regulated document.

Use the original image files, arrange them before conversion, and choose a page size that matches the destination. “Fit to image” preserves each image’s natural proportions, while A4 or Letter creates consistent pages and may add margins. Inspect fine text and page orientation in the exported PDF before deleting or sharing the source images.

Keep an untouched master, write down the intended page sequence, then use reorder, extract or remove as separate operations. Export under a new filename and compare page counts, boundary pages and printed page numbers. Page thumbnails are useful, but they are not enough when pages look similar or the document’s printed numbering differs from its PDF positions.

Load the tool first, open Developer Tools, clear the Network list, then add and process a harmless test PDF. Inspect requests made after file selection: application code may have loaded earlier, but there should be no POST, PUT or request payload containing the document. Repeat the test after a hard refresh and distinguish clearly labeled server-assisted features from local ones.
