About this tool
This page prepares a 300 × 400 pixel portrait photo for an application. The picture is scaled and cropped from the centre so that the result is exactly 300 × 400 pixels, with no stretching, and compressed to stay under 100 KB. Add your photo, check the preview, and download. You can also rotate, flip or crop the picture first so that the face, signature or subject sits where you want it. Nothing is uploaded and there is no watermark.
How to get a 300 × 400 picture Add the picture and start. The tool fills the 300 × 400 frame by scaling the picture until both sides are covered and cutting off what sticks out, so the proportions of your subject are kept. If you want to choose which part stays, use the crop view first, then export. The file is then saved as a JPG and its quality is lowered step by step until it is below 100 KB.
Getting a good result Start from the biggest, sharpest original you have. Enlarging a small picture to 300 × 400 cannot add detail, so a small source will look soft. Keep the subject centred, because the edges are the part that gets cut. For portraits, leave a little room above the head.
Checking the size After export you see the real pixel size and file weight next to the preview. If the receiving form uses millimetres or inches, remember that pixels = inches × dots per inch; this tool gives you the pixel version, which is what upload forms measure.
Privacy Photos of faces, signatures and documents are sensitive. Here everything is done inside your browser, so the picture never leaves your device.
Tips for best results
Work on a copy of your file and keep the original until you have checked the result. Open the output before you send it to a portal, an employer or an office, and look at every page. If a size limit applies, check how the receiving site measures it, because some count a kilobyte as 1000 bytes and others as 1024. All processing happens inside your browser tab on your own device, so large files depend on your device memory and may take a little longer on a phone.

No. The aspect ratio is kept and the overflow is cropped. Use the crop view if you want to pick the area yourself.
Can I also limit the file size?
Yes. This preset also keeps the file under 100 KB.
Is my photo uploaded?
No. It is processed in your browser and never sent to a server.
Which file types work?
JPG, PNG, WebP and HEIC. The result is saved as a JPG, or PNG if you pick it.
Does it work on a phone?
