Type the file size you need, like 1 MB, and get a PDF that fits.
You’ll choose a target size, such as 1 MB or 500 KB.
Runs on your device. Nothing uploaded.
Or drop files anywhere on this page.
Upload forms and email limits often cap attachments at a fixed size. Instead of guessing at quality settings, you tell Foldline the size you need, such as 1 MB or 500 KB, and it picks the best image quality that fits. Text and graphics are left alone, so what you can select and search today still works afterwards. If your PDF is already under the target, it is left untouched.
When you choose a PDF, your browser reads it into memory and the code on this page edits it there. The file is never sent to Foldline’s servers or to anyone else; you can confirm this by watching the network tab in your browser’s developer tools.
Most of a PDF’s weight is usually photos and scans. Foldline recompresses those images and searches for the highest quality that still fits under your target, leaving text, fonts and vector graphics exactly as they were.
Yes. By default only the images inside the PDF are recompressed. If you press “Shrink further” after a miss, pages are converted to images, and then the text can no longer be selected or searched. That second step is always your choice.
Foldline shows the smallest size it could reach while keeping your text. From there you can pick a slightly larger target, remove pages you don’t need, or choose to convert pages to images for a smaller file.
Text and vector graphics are already compact, so there is little to gain without turning pages into images. Foldline says so rather than making the file bigger.
The result is at or just under your target when it can be reached, but not exactly equal to it. Sizes use 1 MB = 1,000,000 bytes, which is the strictest common convention.
No. Foldline opens and edits your PDFs with code that runs inside this browser tab. The file is read into your device’s memory, processed there, and handed back to you as a download. Nothing is sent to a server, and closing the tab discards it.
Yes. If a PDF needs a password, Foldline asks for it as soon as you open the file, then works on an unlocked copy inside your browser. You need to know the password: Foldline cannot guess or recover a forgotten one. Use the Remove password tool if you want to save an unlocked copy.
