Frequently asked questions
- Is my image uploaded to a server?
- No. Everything happens inside your browser using the Canvas API. Your image data never leaves your device.
- What does the aspect ratio lock do?
- When locked, typing a new width automatically recalculates the height to keep the original proportions, and vice versa. Turn it off to set width and height independently — useful for cropping to an exact slot.
- What output formats are available?
- JPEG, PNG, and WebP. JPEG is best for photos; PNG is lossless and supports transparency; WebP offers smaller file sizes and is supported by all modern browsers.
- What image formats can I upload?
- Any image your browser can decode: JPEG, PNG, WebP, GIF, BMP, AVIF, and SVG. If the browser can display it, the resizer can process it.
- How large can the output image be?
- The practical limit depends on your browser and device memory. Very large dimensions (above 8000 × 8000) may fail or be slow. For typical web and social media sizes, there is no issue.
