Exact pixels, zero guesswork

Every platform wants its own size: Instagram crops squares, YouTube rejects thumbnails under 1280 px wide, X stretches headers into 1500ร—500. Instead of memorizing numbers, pick the preset and drop your images โ€” the resizer computes the crop, scales with high-quality interpolation and hands back a file that fits the slot exactly.

"Fill & crop" gives you the exact target size by trimming the overflow evenly from both edges โ€” the mode you want for social slots. "Fit inside" never crops, it just shrinks until the image fits the box โ€” the mode you want for emails and documents. Batch works everywhere: drop thirty photos, get thirty resized copies.

Frequently asked questions

Will resizing reduce quality?
Downscaling with high-quality interpolation keeps images crisp โ€” that is the normal direction. Upscaling beyond the original size cannot invent detail; the result will look soft.
What does "Fill & crop" do exactly?
It scales the image until the target rectangle is fully covered, then trims the overflow evenly from the sides. You get the exact size with no distortion โ€” some edge content is cropped away.
Can I resize many images at once?
Yes โ€” drop any number of files and each is resized with the same settings and downloaded automatically. No queue, no per-file limits, nothing uploaded.
