Local Processing (Offline Capable)
PDF Preflight Check
PDF preflight check for prepress — 300 DPI resolution, font embedding, 3mm bleed, CMYK/RGB colors and PDF/X transparency, with an ISO 12647 score.
Local Processing (Offline Capable)
Compress PDF
Compress PDF files in your browser — light lossless, recommended, and extreme tiers, plus a target-size mode with real-time stats on size and savings (local and free, no upload for files up to 10MB); larger files can use the Pro cloud path (sign-in required).
Local Processing (Offline Capable)
PDF Invert Colors & Dark Mode
Invert PDF colors into comfortable OLED dark mode, classic negative inversion or warm sepia paper tint for night reading and toner-saving printing. Private by design — files never leave your device.
Local Processing (Offline Capable)
Flatten PDF
Flatten PDF form fields into read-only page content so a filled form can't be edited after you share it. Processing runs entirely in your browser — free, no account, no upload; a file with no form fields comes back as a re-saved optimized copy.
Cloud Processing (Encrypted)
Linearize PDF (Fast Web View)
Linearize PDF files for Fast Web View so page 1 renders in the browser while the rest streams in over byte-range requests. The qpdf engine runs on PDFLean's encrypted cloud servers (free account required, billed against your plan quota).
Local Processing (Offline Capable)
Convert PDF to PDF/A
Convert PDF to PDF/A locally with an embedded sRGB ICC or CMYK named condition; device color space stats and validation limits are reported honestly.
Local Processing (Offline Capable)
Remove Metadata from PDF
Remove metadata from PDF files — title, author, subject, keywords and XMP are cleared before sharing; for scripts and attachments use Sanitize.
Local Processing (Offline Capable)
Compress PDF to 200KB
Compress PDF to 200KB or any target size from 20KB to 1MB — the page iteratively recompresses until the result fits the limit, running locally in your browser, free, with nothing uploaded.
Local Processing (Offline Capable)
Grayscale PDF (Rasterized)
Grayscale PDF conversion for ink-saving prints — the default rasterizes pages into images (text not selectable), or choose Images only to grayscale embedded images while keeping text selectable. Runs in your browser, free, with no upload.
Local Processing (Offline Capable)
Repair Damaged PDF
Repair damaged PDF files locally — structural health check with error codes and severity, deep repair and page-by-page rescue; encrypted files need prior decryption.
