Optimize PDF
Make PDFs smaller, repair damaged files and add searchable text to scans.
Compress PDF
Compress PDF reduces the file size of a PDF by re-encoding it with Ghostscript and downsampling the images inside, at one of four quality levels.
Repair PDF
Repair PDF rebuilds a damaged or unreadable PDF's internal structure with qpdf, falling back to Ghostscript, so the file opens again in normal viewers.
OCR PDF
OCR PDF runs Tesseract over each scanned page and adds an invisible text layer behind the image, making the document searchable and its text selectable without changing how it looks.
About these tools
Compression re-encodes images to save space, so higher levels visibly reduce image quality while leaving text sharp. Repair rebuilds a broken file's internal structure, and OCR adds an invisible text layer without altering the visible page.
Every tool in this category is free, needs no account and adds no watermark. Files are processed on our own server and deleted automatically within one hour.
