Optimize PDF tools
Compress, resize, flatten, and clean up PDFs.
Five ways to make a PDF smaller, tidier or cheaper to handle without changing what it says. Compress PDF rasterises each complete page and re-embeds it as JPEG — expect a reduction on scans and photo-heavy decks, but selectable text, links, forms and annotations are removed. It refuses the download when that trade-off does not produce a smaller file unless you explicitly choose the rasterised result anyway. Resize PDF scales every page to a target size such as A4 or Letter, which is what you want when a file built for one paper standard has to be printed under another.
Flatten PDF merges form fields and annotations into the page itself, so filled values and comments become fixed content that no viewer can edit or quietly drop. Remove blank PDF pages finds the empty sheets a duplex scanner leaves behind and deletes them. Grayscale PDF either rewrites supported vector colour operators while leaving embedded photos alone, or rasterises the full page appearance to grayscale. Printer drivers can still use colour inks unless the print job is configured separately.
Compression is usually the first thing anyone searches for when an email bounces on an attachment limit, and it is normally solved by uploading the file to whichever site ranks first that day. Doing the work in the browser removes that step entirely: the document is decoded, re-encoded and written back on your own machine, so a file too sensitive to upload is not too sensitive to compress.
Compress PDF
Rasterize pages as JPEG to shrink scan-heavy or photo-heavy PDFs.

Scale every page to a different size (A4, Letter, custom).
Flatten PDF
Flatten form fields, with best-effort painting of annotation appearances.
Remove blank PDF pages
Detect and drop blank pages automatically.
Grayscale PDF
Convert a color PDF to grayscale for cheap black-and-white printing.
