You can upload JPG, PNG, WebP, GIF, BMP, AVIF, or HEIC (the default format on iPhone photos). Output as JPG, PNG, or WebP.

Yes — that's the whole point. Turn on any combination of maximum file size, width/height, crop, rotation, and output format, and CrispPic applies all of them in a single pass.

Yes, with no account, no watermark, and no limit on how many images you process.

It binary-searches the encoding quality until it finds the highest quality that still lands under your target. If the image can't fit at any quality, it's resized down and the search runs again.

The result is guaranteed to be at or under your target, but landing exactly on it isn't possible — we always err on the safe side rather than going over.

Common examples: government and visa application portals, job application forms, e-commerce product listings, and forums or CMSs with upload limits.

The height is calculated automatically to preserve the original aspect ratio — the image won't be stretched or squashed.

Yes — with the aspect ratio locked, CrispPic fits your image inside the box you set without stretching it. Unlock it if you specifically want an exact, possibly non-proportional, size.

Yes — turn on 'Maximum file size' as well and both requirements are applied together in one pass.

Free-form, square (1:1), landscape (4:3), portrait (3:4), widescreen (16:9), story (9:16), or a custom ratio you type in.

Yes — click the pencil icon next to 'Crop' to reopen the editor, or the × to remove the crop entirely.

Yes — turn on 'Maximum file size' after cropping and both are applied together.

Output as JPG, PNG, or WebP. Input accepts JPG, PNG, WebP, GIF, BMP, AVIF, and HEIC/HEIF.

Yes — JPG has no transparency channel, so transparent areas are filled with white. CrispPic warns you before it happens; choose PNG or WebP to keep transparency.

Yes. Upload a .heic file and CrispPic converts it automatically before applying whatever format you choose.
