Resizor offers aspect ratio locking for common formats (1:1 for social squares, 16:9 for widescreen, 9:16 for Stories and Reels), freeform cropping, and pixel-precise dimension entry. The cropping runs via WebAssembly (wasm-vips) for lossless cropping of PNGs and high-quality output for JPEG and WebP. Your image is never uploaded — all processing happens on your device.

Frequently Asked Questions

Can I crop an image to a specific size in pixels?

Yes. Resizor lets you enter exact pixel dimensions for your crop area. You can also resize after cropping to get precise final dimensions.

What aspect ratio should I use for social media?

Common aspect ratios: Instagram feed square = 1:1, Instagram portrait = 4:5, Twitter/X header = 3:1, Facebook cover = 205:78 (roughly 2.63:1), YouTube thumbnail = 16:9, TikTok/Reels = 9:16.

Does cropping an image reduce file size?

Yes. Cropping removes pixels outside the selected area, which reduces the file size proportionally to the area removed. A centre crop of 50% of the original area will produce a file roughly 50% smaller (for the same format and quality).

Can I undo a crop in Resizor?

Yes. Before downloading you can reset the crop and start over. Once you download, the crop is applied permanently to the saved file.

What image formats does the crop tool support?

Resizor's crop tool supports JPEG, PNG, WebP, AVIF, and GIF. The output is saved in the same format as the input unless you choose to convert.
