Crop an image to an exact pixel size. Type the width and height you need, lock the ratio if you like, and download a crop that matches the slot precisely.

Some images have to be an exact size — a 1200×630 social card, a 512×512 icon, a 300×250 banner, a 150×150 thumbnail. Eyeballing a drag almost never lands on the right pixels. Here you type the width and height and the crop comes out at exactly that size. Turn on the aspect lock to keep the shape while you reposition, or leave it off to set width and height independently.
This tool crops your chosen region and outputs it at the pixel size you set, sampling from the full-resolution source so the result stays sharp. If the size you type is smaller than the area you framed, the crop is scaled down to fit; if it is larger, the pixels are kept at source resolution where possible. For transparency-sensitive work, export PNG or WebP; for the smallest photo files, choose JPG.
Setting an output size makes this an image cropper and resizer in a single step: crop the region you want, then have it come out at the exact pixels you typed — effectively image resize and crop online. Use it to crop an image to a size a platform requires, shrink an oversized export, or standardize a set of thumbnails. Lock the ratio to keep proportions, or set width and height independently. For a fixed shape across many files, pair it with the aspect ratio cropper or the batch cropper.
Knowing the target pixels saves guesswork. A few that come up often: avatars 512×512; Instagram post 1080×1080 (or 1080×1350 portrait); YouTube thumbnail 1280×720; X / Twitter header 1500×500; Facebook cover 820×312; LinkedIn banner 1584×396; Pinterest pin 1000×1500; TikTok / story 1080×1920; favicon 32×32 or 64×64; app icon master 512×512. Type the width and height and the crop comes out at exactly those dimensions; lock the ratio first if you want the shape fixed while you position the frame. For the platform sizes above, the dedicated scenario pages — such as the YouTube thumbnail cropper, Pinterest pin cropper and TikTok cropper — preset the ratio so you only have to frame and download.
Everything in the Crop by Size happens locally in your browser, so nothing is uploaded and there is no waiting on a server, no watermark and no sign-up. That makes it private enough for sensitive pictures — ID photos, documents, personal snapshots — and it even works without a connection once loaded. The same page runs on desktop and mobile, with draggable handles for both pointer and touch input, and you can keep cropping more files without starting over. Save your result as a lossless PNG or WebP to keep transparent areas, or as a JPG for a smaller photo file. Lock a ratio, switch to a circle, or type exact pixels — whatever the task needs.
Drop it in. The aspect lock is on so width and height stay in proportion.
Enter the pixels you need. Unlock the ratio to set them independently.
Export at the exact size in PNG, JPG or WebP.
Yes. Type the width and height and the crop is produced at exactly those pixels.
Yes. Turn on the lock and entering one dimension sets the other automatically.
Yes. The crop samples from the full-resolution source, so quality is preserved as far as the size allows.
Yes, when you export as PNG or WebP. JPG fills transparency with white.
No. Everything is computed in your browser; the file is never uploaded.
