Resize then cap

SizeCap

Resize photos to a pixel box, then a size cap

Set a width and height, or a longest edge. SizeCap can letterbox on white or crop to fill. It does not detect faces or replace a background. An optional size cap then writes baseline JPEGs on this device.

Files never leave this device

Your photos

    Pixel size

    Pick a box or a longest edge. Fit keeps the whole photo on a white background. Fill crops to the box. Neither finds a face.

    Optional size cap

    Leave this blank to keep the resized pixels at high JPEG quality. If you enter a limit, each JPEG is compressed on its own to that size — not as a combined batch.

    Common limits

    Per-file, not a combined cap. For several photos that must share one total, use the photo compressor. SizeCap counts 1 KB as 1,024 bytes.

    How resize works

    Choose a pixel rule, add photos, and optionally a per-file size cap. SizeCap writes JPEGs in your browser.

    1. Choose pixels

      Enter a width and height, or a longest edge. Pick fit-inside (letterbox on white) or fill-and-crop. There is no face detection.

    2. Add photos

      JPEG, PNG, WebP, GIF, BMP, and AVIF work. HEIC does not.

    3. Save JPEGs

      Check the pixels and file size, then download each JPEG or a ZIP.

    Frequently asked questions

    Are my photos uploaded anywhere?

    No. Resize and JPEG encoding run in this browser.

    Will this make a passport or visa photo?

    No. It can fit a box such as 600×600 or 630×810, but it will not find a face, fix a background, or claim biometric compliance. Crop in another editor first if the form needs that.

    What is the difference between fit and fill?

    Fit keeps the whole photo and adds white bars if the box is a different shape. Fill fills the box and crops the overflow. Neither stretches the photo out of proportion.

    Is the size cap for each photo or all of them?

    Each photo. Use the homepage compressor when several JPEGs must add up to one total.

    Does this write baseline JPEG?

    Canvas JPEG in current browsers is baseline, which is what most forms want. The result labels the file as JPEG. SizeCap cannot promise a portal will accept every encoding quirk.
