Reduce file size without losing quality; works right in your Samsung browser.
Open Compress PDF Tool →That 15MB PDF sitting in your My Files app is too big to email, and Samsung's built-in tools won't help you shrink it. Meanwhile, every "free" PDF app in the Galaxy Store wants a subscription or plasters watermarks across your documents.
PDFGadget solves this problem directly in Samsung Internet or Chrome. No downloads, no sign-ups, no limits. Your PDF gets compressed right on your Samsung device, never leaving your phone. The entire process takes about 30 seconds.
Launch Samsung Internet or Chrome on your Galaxy phone. Navigate to pdfgadget.com/compress-pdf/. The page loads quickly and works on any Samsung device running One UI.
Tap the upload area or the "Choose File" button. Samsung's file picker will open—check the Downloads folder, My Files, Google Drive, or Samsung Cloud depending on where your PDF is stored. Select the file you want to compress.
PDFGadget offers multiple compression settings. For documents with mostly text, the high compression option works great. If your PDF contains photos or graphics where quality matters, choose medium compression to balance size reduction with visual clarity.
Tap the compress button and wait a few seconds. The compression happens entirely within your Samsung browser—your file never gets uploaded to any server. You'll see the original size and new size displayed so you know exactly how much space you saved.
Tap the download button. On Samsung devices, the file typically saves to your Downloads folder. You can also tap the Share icon to send it directly via email, Samsung Messages, WhatsApp, or any other app—no need to hunt for the file afterward.
Samsung phones are powerful, but One UI doesn't include native PDF compression. PDFGadget fills that gap without the hassle of installing yet another app.
Once compression finishes, Samsung gives you several options for storing or sharing the smaller file:
Samsung's My Files app sometimes needs a moment to index new downloads. Pull down to refresh the Downloads folder. If it still doesn't appear, open Samsung Internet's download manager by tapping the three-dot menu and selecting "Downloads."
Some Samsung devices have aggressive download warnings enabled. When prompted, tap "Download anyway" PDFGadget is safe and doesn't run any executable code. You can also try Chrome if the issue persists.
Samsung's memory management can refresh browser tabs when you multitask. Before switching to another app, wait for the compression to complete and download immediately. Avoid switching apps mid-process.
Budget Galaxy devices and older models may process large PDFs more slowly since compression runs on your phone's hardware. For PDFs over 50 pages, expect 15-30 seconds. Close other apps to free up memory if needed.
Absolutely. PDFGadget works great in Samsung Internet, many users prefer it because of Samsung's built-in ad blocking. Chrome works equally well if that's your default browser.
Yes. PDFGadget works on any Samsung Galaxy tablet running One UI, including the Tab S series and Tab A series. The larger screen actually makes selecting files even easier.
Higher compression levels do reduce image quality somewhat. For documents where image clarity is critical, use the medium or low compression setting. Text remains crisp at all compression levels.
PDFGadget can handle PDFs up to 100MB. For extremely large files, processing time increases since everything happens locally on your Samsung phone's processor rather than on a server.
Currently, PDFGadget compresses one PDF at a time. For multiple files, compress each one individually—the process is fast enough that batching usually isn't necessary.
No. The compression algorithm focuses on optimizing images and reducing file bloat. Text remains fully searchable and copy-able in the compressed PDF.
