PDF files can get large quickly, especially when they contain scanned pages or high-resolution images.
Why PDF Size Matters
Large PDFs are slow to email, hard to upload, and annoying to open on mobile devices. Most email providers cap attachments at 25MB, meaning sharing extensive documents can become a massive headache.
How pdf62 Compresses PDFs Locally
Unlike most online tools, pdf62 uses WebAssembly to process your file entirely in the browser. When you upload your PDF to pdf62:
- Zero Uploads: Your file never leaves your machine.
- Instant Processing: Without relying on network speed, compression happens instantly on your device.
- Total Privacy: Sensitive documents (invoices, legal papers, medical records) remain strictly private.
The Best Settings for Compression
To get the most out of your compression without degrading the document:
- For Text-Heavy Documents: Use medium compression. Text is highly compressible.
- For Image-Heavy Documents: Experiment with compression levels to find the right balance between file size and image clarity.
