Pixel Resize FAQ
Answers to common questions about pixel based resizing for screens.
Pixels describe the digital dimensions used by screens, while inches or cm describe physical size for print. If you need web or app assets, pixel sizing is the most reliable because it maps directly to CSS and device resolutions.
Yes. Turn on the aspect ratio lock and the tool keeps the same proportions as you edit width or height. This prevents stretching and keeps photos, logos, and UI screenshots looking natural. Unlock it for custom stretching when needed.
Resizing changes the pixel grid, so some loss is possible when scaling down or up. The quality slider lets you control compression for JPG and WebP so you can keep sharpness while reducing file size. Avoid extreme upscaling of small originals.
You can export JPG, PNG, or WebP. Use PNG for transparency or crisp text, JPG for photos, and WebP for modern web delivery with smaller files and good quality. Use PNG when you need transparent UI layers. This keeps logos clean on overlays.
For high density displays, export at 2x or 3x the CSS size. For example, if a slot is 400px wide, resize to 800px and deliver the 2x file so it stays sharp on retina devices. This avoids blurry icons on high resolution screens.
The estimate is based on current dimensions and compression settings. Actual size can vary with image content and format, especially for photos with complex detail or flat color blocks. Images compress differently at the same quality.
There is no strict limit, but extremely large images can be slow in the browser. If processing stalls, resize in steps or reduce the target size to keep things responsive. Closing other tabs can help with memory.
No. Everything runs locally in your browser and files are not uploaded or stored. This makes it safe for client assets and internal design work. It is suitable for NDA and pre launch materials. Great for client reviews and approvals.
Yes. You can use the tool for free without creating an account, entering a credit card, or installing software. There are no usage caps or watermarks, so you can edit as many images as you like and download full-quality results any time.
No. All processing happens locally in your browser, which means files stay on your device and are never sent to our servers. Once you close the tab, nothing is stored on our side, making it safe for personal and client work.
