DoxlyShrink a document that is too big for an email or an upload limit.
Almost every oversized PDF is a scan. A phone photographing ten pages easily makes a twenty-megabyte file, and the portal you must submit it to often caps at two.
Doxly redraws each page at lower resolution and re-encodes it as JPEG, which is where the saving comes from. Understand the trade before you use it: text in the output becomes part of a picture, so it can no longer be selected, searched or read aloud. For a scan that is no loss, because the text was already an image. For a PDF exported from Word it is a real downgrade, and you are usually better off exporting a smaller file from the original.
If you're shrinking this file because you're about to send it over a weak connection, the good news is the shrinking itself doesn't need one: the twenty-megabyte scan never leaves your device to get compressed, so the slow part of your day is whatever you do with the smaller file afterwards, not this step.
For a photographed or scanned document, sixty to ninety percent is common. For a PDF exported from a word processor there may be no saving at all, and Doxly will tell you when your original is already the smaller file.
Compression turns each page into an image. That is what makes the file small, and it is why text stops being text. If you need searchable text, keep the original.
Start with Balanced. It usually clears a five-megabyte limit while keeping a scan readable. Drop to Smallest file only when a strict cap forces you to, and check before sending.
The PDF was already efficiently compressed, so re-encoding added size rather than removing it. Doxly detects this and tells you to keep your original.
