Reduce PDF file size while maintaining quality
Most other tools only offer a few fixed levels, leaving you to guess at the result. With Dely PDF, you set the exact target size you want, so the outcome is certain, not a guessing game.
Beyond automatic compression, fine-tune every detail in Advanced mode. Strip metadata, flatten forms, switch to grayscale, or cap image resolution. Part of Dely PDF Pro.
Curious what's making your PDF large? The Audit Content tool breaks down every contributor, from fonts and images to bookmarks and document overhead, so you know exactly what to trim. Part of Dely PDF Pro.
Add multiple PDFs and compress them all in one action, with the same settings, instead of doing it file by file. Part of Dely PDF Pro.
Every compression step runs right in your browser. No file is ever sent to a server, so your personal documents never leave your device.
Many recruitment portals only accept PDFs under 1-2 MB. Compress your cover letter, diploma, and transcript first so they don't get rejected over file size.
Scanned lab reports or theses often end up dozens of MB. Shrink them before uploading to your campus portal or sending them to a lecturer or teacher.
WhatsApp and some email services cap attachment size. A smaller PDF uploads faster and rarely fails.
Photos or scans from a phone camera are often huge due to high resolution. Compress them without blurring the text or signature.
Add or drag a PDF from your device. Everything runs in your browser, never sent to a server.
Use Recommended for a balanced result, or set your own Target Size, like under 2 MB. Unlike other tools that only offer a few fixed levels, you won't have to guess at the result.
Dely PDF shows a before-and-after size comparison right away. Download it once you're happy with the result.
