MSRX PDF Compressor makes PDFs smaller without turning your text into pictures. Most PDF compressors flatten every page to an image. The file shrinks, but you lose selectable text, search, links, and anything a screen reader can use. This one looks at each page first. Pages with real text keep it. Pages that are scans or photographs get re-encoded, which is where nearly all the saving in a scanned document lives anyway. TEXT STAYS TEXT A 135-page workbook came out 33% smaller with all 138,000 characters still selectable and searchable. A 224-page scanned textbook went from 100 MB to 9 MB. The difference is the document, not the setting — and the app tells you which one you have before you commit. FIT UNDER A LIMIT Tell it the limit your email or upload form imposes — 5, 10, 20 or 25 MB — and it works out the settings for you, testing real pages rather than guessing. If it cannot reach your limit, it says so and hands back the smallest file it managed. It will not pretend it succeeded. SEE WHERE THE MEGABYTES ARE Before you compress, the app breaks the file down: images, fonts, page content, overhead. Then it tells you plainly what to expect — "10 of 28 pages are scans. Those compress well; the rest keep their text." COMPARE BEFORE AND AFTER Put the original and the result side by side, page by page, and confirm for yourself that nothing was lost. ALSO IN THIS VERSION • Compress several PDFs at once, with per-file results • History, with a running total of everything you have saved • Greyscale conversion for scans and photographs • Compress from any app's share sheet, without opening this one • A Shortcuts action, for compressing as part of an automation • Full Dark Mode, Dynamic Type, and VoiceOver support HONEST ABOUT WHAT IT CANNOT DO Compression works on images. A document that is mostly text and embedded fonts has very little to give, and the app says so up front instead of letting you find out afterwards. Scanned documents are where you will see the dramatic numbers. PRIVATE BY DESIGN Everything happens on your iPhone or iPad. Your files are never uploaded, and the app has no analytics, no accounts, and no network access at all. FILE LIMITS Up to 500 MB and 2,000 pages per document. Free. No ads, no subscriptions, no in-app purchases.

About

Feather PDF

Read full description

Feather PDF gives you the full paid-PDF-suite toolbox — completely free, with no sign-ups, no daily limits, and no watermarks stamped on your files. The difference? Everything happens on your iPhone. Other PDF apps upload your documents to their servers to process them. Feather PDF never does. Your contracts, tax forms, medical records, and IDs stay on your device from start to finish — which also makes it fast, and means it works with no internet connection at all. NINE TOOLS IN ONE APP • Merge PDF — combine any number of PDFs into one. Drag to reorder with live page thumbnails. • Split PDF — pull out specific pages ("1, 4-7"), save every page separately, or split into equal chunks. • Compress PDF — shrink files for email with four quality presets, with a live preview of the quality trade-off before you commit. • Organize PDF — see every page as a thumbnail, then reorder, rotate, or delete pages with a tap. • Rotate PDF — fix upside-down scans in seconds. • Images to PDF — turn photos, screenshots, JPG, PNG or WebP images into a clean PDF with your choice of page size and margins. • PDF to Images — export every page as a high-resolution PNG or JPG. • Watermark — stamp "CONFIDENTIAL" (or anything else) across every page, with a live preview on your actual document. Control size, color, opacity, angle, tiled or centered. • Page Numbers — add page numbers in any corner or centered, in formats like "3 of 12", previewed live on your file. WHY PEOPLE SWITCH TO FEATHER PDF • Private by design — files are processed on your device and never uploaded. There is no server to trust, because there is no server. • Actually free — no subscription, no "3 files per day" limit, no watermark ads stamped onto your documents. Supported by a small banner ad instead of your data. • No account needed — open the app and get to work. • Works offline — on a plane, in a basement, anywhere. • Live previews — see exactly what your watermark, page numbers, or compression will look like before you apply them. • Fast — no upload/download round-trip means big files process in seconds. • In your language — available in English, Spanish, French, German, Portuguese, Japanese, and Chinese. PERFECT FOR Combining scanned receipts for expense reports, shrinking attachments that bounce back from email servers, extracting the two pages you actually need from a 90-page manual, watermarking proposals before sending them out, numbering contract pages, and turning photo batches into shareable PDFs. Download Feather PDF and stop paying subscriptions for things your phone can do by itself.
