Optimize a PDF for sharing, viewing or printing. Reduce file size, improve scan readability, prepare Fast Web View, try to repair structural problems or flatten interactive content. Choose the tool for your goal: a smaller download, clearer pages and faster web delivery require different operations.
Recolor text and images, change the background, and give every page a new tone.
Cleaner backgrounds. Clearer notes.
Smaller files. Easier sharing.
Find a clearer balance of light and dark.
A clean monochrome version of your document.
Straighten tilted scanned PDF pages automatically or with a chosen angle.
Create an archival PDF/A copy and validate it before downloading.
Check PDF/A compliance and download a validation report.
Check whether your PDF is ready for a print shop.
Keep what matters. Remove text, images or shapes with a live preview.
Make form values and annotations permanent parts of your PDF pages.
Try rebuilding a damaged PDF so its recoverable pages can open again.
Linearize your PDF for earlier first-page loading in compatible web viewers.
Expand compressed PDF content streams for inspection and further processing.
From paper to a clean PDF. Scan, straighten, and bring every page together.
Prepare a report for an upload limit, make archived scans easier to read or publish a document for online viewing. Check the result against the original: optimization can affect images, selectable text, forms and file size in different ways.
Compress PDF accepts input up to 300 MB and offers compression profiles plus an image-resolution setting. Compare small text and detailed images before choosing the strongest reduction. Existing compression and page content determine the savings; an already optimized PDF may not become smaller.
Use Contrast PDF for brightness, contrast, automatic levels or local contrast. Enhance Scanned PDF provides clean-background, black-and-white and colored-note profiles. Preview the current page and use shared or individual page settings. These tools create image-based output, which may be larger than the original.
Fast Web View prepares a PDF for progressive loading in compatible viewers and hosting setups. Repair PDF attempts supported structural repairs. Flatten PDF turns supported interactive content into page content, while Decompress PDF expands internal streams. These operations solve different problems and do not guarantee smaller files.
A few answers to help you choose the right tool.
Compress PDF accepts an input PDF up to 300 MB. Page, processing and output limits still apply, and large files need more time and memory. Other optimization tools have their own limits.
No. Savings depend on images, fonts, existing compression and the selected settings. Already optimized files may shrink very little. Compress PDF keeps the smaller eligible source or processed result when conversion would otherwise increase the size.
Yes. Image resolution sets a specific downsampling target and can override the resolution implied by a compression profile. Lower values can reduce size but soften images and small scanned text. Preview the output before using it.
Compression aims to reduce file size. Fast Web View reorganizes a PDF so compatible viewers can begin reading before the whole file downloads. Progressive loading also depends on server support for partial-file requests.
No. It attempts supported structural repairs but cannot guarantee recovery of missing or badly damaged content. Keep the original and check every important page in the repaired copy.
The scan-enhancement and contrast tools generate image-based pages. They do not retain interactive forms or add OCR, and an existing selectable text layer can be lost. Use these tools for visual cleanup and retain the original when editability matters.
Not necessarily. Flattening changes supported interactive content into page content. Decompression expands internal streams and can increase size. Use Compress PDF when reducing the file size is the main goal.
