Optimize & Repair
Compress, optimize, and repair PDF files
Compress PDF
Compress a PDF in your browser: pick a level or a target size, downscale images and strip metadata. Up to 10 files at a time, and nothing is uploaded.
Fix Page Size
Put every page of a PDF on one size, such as A4 or Letter, by fitting, filling, stretching or centring the content. Links and form fields are not kept.
Linearize PDF
Linearise PDFs for Fast Web View with qpdf running in your browser, so the first page can appear before the whole file downloads. Up to 10 files at once.
Page Dimensions
Analyze PDF page sizes. View dimensions of all pages in your document.
Remove Restrictions
Remove print, copy and edit restrictions from a PDF you have the right to change, with qpdf in your browser. A file with an open password needs it.
Repair PDF
Try to repair a damaged PDF in your browser with qpdf, which rebuilds a broken cross-reference table and rewrites the file. Missing data cannot return.
Deskew PDF
Automatically straighten scanned or tilted PDF pages. Fix skewed documents with precision angle detection.
PDF/A Preparation (Clean-up Only)
This tool does not create PDF/A. It re-saves a PDF with unused objects removed and streams compressed. Convert with a PDF/A tool, then check with veraPDF.
Font to Outline
Remove font dependencies from PDF documents by converting pages to high-quality images. Ensures compatibility across all systems.
PDF Layer Viewer (OCG)
List the layers (optional content groups) in a PDF and see which are on by default. Editing layers does not work in this version. Runs in your browser.
Deep Metadata Sanitizer
Thoroughly wipe author metadata, modification logs, hidden layers, and orphan objects from PDFs for maximum privacy.
e-Ink Reader Optimizer
Optimize PDFs for e-Ink screens via background clearing, Otsu binarization, and morphological text dilation.
Batch Remove Watermarks
Physically scrub watermark strings and XObject images from the PDF content stream without messing up layouts.
Fix Dead Links
Scan all URL actions and link annotations in PDF, detect reachability, and inject redirects.
Auto Scan Deskew
Detect and auto-correct page rotations and alignments on mobile-photo or scanned PDF sheets instantly.
Enhance Handwriting Ink
Extract blue or black handwriting signatures from photos, bleach yellow paper grain, and dramatically boost ink contrast for readability.
