Compress PDF & Photo to KB
Redact, Sign & Upload Limits
Free · Designed for iPad. Not verified for macOS.
Scan the document, sign every place that needs it, and fit the PDF and your photos to the portal's exact size limit.
Upload rejected because the PDF is too large, the photo has the wrong dimensions, or every signature box has to be filled? Scan the document, place your signature everywhere it belongs, fit PDFs and photos to the exact upload limit, and save the finished files to a folder you choose.
FIT THE PDF TO THE EXACT LIMIT
Give the app the limit the destination states — 500 KB, 2 MB, or another value — and it compresses the document towards that limit, and tells you when it cannot reach it. Before you save, it checks the finished size, page count and whether the file opens. A screenshot of the destination's requirements can supply the limit, and you confirm it before use.
PHOTOS AND SIGNATURES AT EXACT PIXELS
Enter 413 x 531 pixels and a 20–50 KB range, or type completely different requirements. Crop the image, and the finished file is measured against the dimensions, size range and format you entered before it can be saved. Works with photos from your library, from the camera, or shared straight from Photos.
SCAN, SIGN AND SAVE IN ONE RUN
Your camera finds the page edges, and you can drag the corners yourself when the page was crooked. Rotate a page, switch it to Enhanced, Greyscale or Black & white, and nudge brightness and contrast — page by page, before anything is saved.
Then place your saved signature on every page that needs it, not just the first, fit the result to the limit and save it to the folder you picked. One pass, one app.
The signature is your own handwriting placed on the page as an image. It is not a certificate-based digital signature.
Save any sequence as a workflow. It remembers the source, signing step, confirmed limit, file name and folder; every run still pauses for you to approve signature placements.
REDACTION THAT REMOVES, NOT COVERS
A black box drawn over text is not redaction: the words are still in the file and can be copied straight back out. This app removes the marked content instead. The areas are painted out and the page is rebuilt from what is left, so those words are no longer part of the page's text. Redact a box, a brush stroke, a single tapped word, or every match in the document.

AN ASSISTANT, ON DEVICES THAT HAVE ONE
On iPhones with Apple Intelligence, the app can read a document and suggest what to do with it. Its suggestions are checked by ordinary code: dimensions, byte limits, page counts, signature placements and the saved file are measured rather than assumed. Requires a compatible device; everything else in the app works without it.
Localized in English, German, Spanish, French, Hindi and Portuguese.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Compressing to a size limit keeps more quality: files stop shrinking as soon as they fit, and the result shows the right size. Results now show the original and compressed size side by side, batch results lead with the total saved, and reading a limit from a screenshot shows the screenshot it read. Page tool titles are translated, plus smaller fixes.
