Yes. Every tool on smartpdfconv.com is completely free to use. There are no registration requirements, no file count limits, no paywalls, and no premium tiers that unlock basic features.
No. Because files are processed in your browser, the only limit is your device's available memory. Even very large PDFs (100+ MB) can be compressed, merged, or split.
No. All tools work instantly without registration. Just open the site, select a tool, and start working with your files.
No. All processing happens entirely in your web browser using WebAssembly (WASM). Your files are never uploaded to, transmitted to, or stored on our servers. We cannot see, access, or recover any file you process.
Most online PDF tools require you to upload your document to their servers. This means your file exists on their infrastructure, and you have no way to verify how long it's stored or who can access it. smartpdfconv processes everything locally in your browser — your file never leaves your device.
We use Google Analytics for aggregate, anonymized usage statistics (pages visited, device types, referral sources). We do not track individual file processing, filenames, or document contents. See our Privacy Policy for full details.
All modern browsers that support WebAssembly — Chrome, Firefox, Safari, Edge, and Opera. We recommend using the latest version for the best performance.
WebAssembly (WASM) is a technology that lets websites run code at near-native speed directly in your browser. This means smartpdfconv can process PDFs as fast as desktop software — without any downloads or installations.
We support PDF files for compression, merging, splitting, rotation, watermarking, and text extraction. For the Images to PDF converter, we support JPG, PNG, WEBP, and GIF images.
PDF compression reduces file size by downsampling embedded images, re-encoding them at lower quality, removing redundant metadata, and cleaning up the PDF structure. Our tool offers light, recommended, and extreme compression presets. Learn more in our compression guide.
Most PDFs can be reduced by 50–90%. Text-heavy PDFs compress less (20–40%), while image-heavy PDFs — scanned documents, photos, presentations — compress the most. The exact result depends on the original content and compression settings you choose.
Yes. Scanned PDFs are typically image-heavy and compress very well — often 50–90%. Our compressor detects the structure and applies aggressive image downsampling for maximum reduction.
If a PDF has an owner password (permissions), most tools can still read and process it. If it has a user password (document open password), you'll need to remove it first. Our tools will show a clear error message if a file is encrypted.
Upload your PDF to our Split PDF tool to see visual thumbnails of every page. Click pages to select them, or type a range like "1-3, 5, 8-10". The extracted pages download as a new PDF.
Yes. Our Images to PDF tool accepts JPG, PNG, WEBP, and GIF images. Upload multiple images, reorder them, choose a page size (A4, Letter, or Fit), and generate your PDF instantly.
Yes. You can use smartpdfconv to process documents for any lawful purpose — personal, educational, or commercial. You own the output files.
