Image tools

Tools that get a photo to meet a requirement: under an attachment size limit, out of the iPhone HEIC format and into JPG, cropped or resized to the pixels a form asks for, several photos joined into one picture or gathered into one PDF, cropped to the 413×531 px Korean passport specification, or stripped of location data before it goes on social media. Colours can be read straight off a picture as hex as well, and the same place flips a photo, hides a face or a number behind a mosaic, puts text on it, or draws a signature as a transparent PNG.

The photo never leaves your device. Conversion, compression and cropping all finish in the browser and only the result is downloaded — so face photos and document scans are never uploaded anywhere.

Image Compressor (target file size)Say the size limit, get the best-looking file that fits under it. Nothing is uploaded.

ExampleAn upload form that rejects your photo — Application forms and government sites often cap attachments at 1MB or 2MB. Set the limit, and the photo comes back just under it instead of being cut to some random quality.

ID Photo Resize & CropDrop a photo, fit it in the frame, save at the exact pixel size. Includes the 413×531 px passport preset. Nothing is uploaded.

ExampleOnline passport application photo — The ministry’s online application accepts 395–431 by 507–550 pixels and recommends 413×531. Choose the passport preset and that is the size you get; the card shows the file size. Over 500 KB, switch to JPG.

HEIC to JPG ConverteriPhone photos that will not open, turned into plain JPG or PNG. Batch, ZIP download, nothing uploaded.

ExampleCopied photos to a Windows PC and they will not open — iPhones have saved photos as HEIC since 2017. Windows Photos, older editors and most upload forms cannot read it. Drop the files here and take JPGs back; the originals stay untouched.
