Frequently asked questions
- How is this different from Crop PDF?
- Crop PDF trims away part of the page, permanently discarding whatever falls outside the crop area. Resize PDF instead scales the whole page — content and all — to a new size, keeping everything visible, just larger or smaller.
- Will my content look distorted after resizing?
- Only if the new size has noticeably different proportions than the original. A same-shape resize (e.g. Letter to a slightly larger custom size with the same aspect ratio) looks identical, just bigger. Changing between very different shapes will stretch content slightly, the same way a photo looks stretched if you resize it without keeping its aspect ratio.
- Is my PDF uploaded anywhere?
- No — resizing happens entirely in your browser. The file never leaves your device.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| PDF ever leaves your device | No — resized in this tab | Yes, uploaded to process |
| Standard size presets | A4, Letter, Legal, A3, A5, Tabloid | Varies |
| Account required | Never | Often, past a certain usage level |
