File and PDF Guides
Clear, practical advice for preparing files, choosing formats, and checking your results. These guides explain the decisions around the tools, not just where to click.
Choosing the right image format
Use JPG for photographs, PNG when you need transparency or crisp interface graphics, and WebP when you want a small file for the web. GIF is useful for short, simple animations but has a limited colour palette. SVG is best for logos and illustrations that need to scale without becoming blurry.

Start by removing blank or duplicate pages, then reorder the document and rotate pages that were scanned sideways. Crop excessive scanner margins last. Keeping the original file until you have checked the downloaded result makes it easy to recover from a mistaken edit.

If a PDF is too large to send, check whether it contains high-resolution photos or scans. Compressing those images usually has the biggest effect. Text-only PDFs may not shrink much. After compression, open the result and check small text, signatures, and scanned details before sending it.
Compress a PDF →Redacting sensitive information safely
Do not rely on a black shape placed over text: the covered text may still be selectable or recoverable. Mark the sensitive areas and inspect the exported file by trying to select and copy the covered content. Keep an untouched original in a secure location in case you need to verify what was removed.
Redact a PDF →Why local processing can be useful
Browser-based processing means the file is read by your device instead of being uploaded to a conversion server. This can be helpful for private paperwork. It also means performance depends on your device and browser memory, so very large videos or PDFs may take longer or fail on low-memory devices.
Learn about Staticvert →Check the result before you rely on it
Conversions between different formats are not always perfectly reversible. Review page breaks, fonts, images, spreadsheet formulas, and document metadata in the downloaded file. For legal, financial, or official submissions, compare the result with the source and keep a copy of both files.
