The report shows the old and new dimensions side by side, as "3424×1925 → 1080×607", before you save.
What 413 × 531 pixels stands for
The preset on this page is 35 × 45 mm at 300 dots per inch, which works out to 413 × 531 pixels. It is the photo size most European passports and identity cards use and the one Schengen visa applications typically ask for, and many countries elsewhere have adopted it. Agencies tweak the details, and an online service may want more pixels than 413 × 531, so the form you are filling in has the final word. The United States is the notable exception: its passport and visa photos are square, a different shape altogether, so for those crop to 1:1 instead of using this preset. Here the Passport photo preset is already selected, so there is nothing to type: drop the photo in and check the result.
Crop first, then resize
Resizing scales the whole frame; cropping removes part of it. A portrait phone photo is 3:4 and a passport photo 7:9, so scaled as it is, the picture either gets narrow bars at the sides, white in a JPEG and transparent in a PNG, which is what the default Contain mode does, or loses a strip at the top and bottom in Cover mode. The clean route is to cut the frame yourself in Crop Image with the custom ratio set to 7:9, placing the head where the form wants it, and then run the result through the preset here, which lands it at exactly 413 × 531. If you carry on from the crop page instead of coming back, set Resize by to Preset and pick Passport photo. Enlarging is blocked by default: a source smaller than that is kept at its own size, so start from a full-resolution shot, not a thumbnail.
Background, head size and the other checks
Pixel dimensions are only the first thing a form checks. Most ask for a plain, evenly lit background, usually white or light grey, with no shadow behind the head. If the wall behind you is busy, a new shot against a plain wall is the safest fix, because some agencies reject edited photos; where the rules allow it, Remove Background can swap the background for flat white before you crop. Forms also specify how much of the frame the face fills, commonly around three quarters of the height from chin to crown with the eyes in the upper half, and they want a recent picture with a neutral expression and no filters. Crop to those proportions before resizing, because the preset keeps whatever framing it is given.
File size and format for the upload
Almost every portal takes a JPEG, some refuse PNG, and many cap the file somewhere between 50 and 240 KB. Resizing keeps the format it is given. A JPEG stays a JPEG, and at 413 × 531 pixels it is small by nature, usually under 100 KB at the quality this page uses; a PNG, which is what Remove Background hands back, stays a PNG and weighs more. Either way, if the form wants a JPEG or a smaller file, run the result through Compress Image with the exact target: it saves a JPEG by default, and with Allow resizing if needed switched off, the 413 × 531 stays intact. Keep the full-size original for the next form that asks for different numbers. On paper, 413 × 531 pixels printed at 300 dpi come out at 35 × 45 mm to within a fraction of a millimetre, so the same file can go to a photo printer for a paper application. The resize works from a phone too, in Safari or Chrome, with the result saved through the Share sheet or into Downloads.
Your file stays on your device
Decoding, resampling and re-encoding run inside your browser tab through WebAssembly. No image is uploaded, no server ever sees it, and everything is cleared from memory the moment you close the tab.
Frequently asked questions
Does resizing down hurt image quality?
Shrinking an image loses some fine detail by necessity, but the Lanczos3 filter used for downscaling here is one of the sharpest resampling algorithms available, well ahead of the blurrier box or bilinear filters built into many simple tools. At normal reduction ratios the result looks crisp, not soft.
Why can't I enlarge my image by default?
Making an image bigger than its original resolution does not recover detail that was never captured. It just spreads existing pixels over more space, which looks soft rather than sharp. The "no upscale" option is on by default to stop this from happening by accident; switch it off if you specifically want to force a larger size anyway.
What's the difference between contain, cover and stretch?
They only matter when your target shape does not match the source's proportions. Contain shows the whole photo with padding added around it. Cover fills the frame completely by cropping the overflow, centered on the image. Stretch forces the exact box and distorts the picture if the proportions do not match.
What size do I need for Instagram?
The square post preset is 1080×1080 pixels, and the story/reel preset is 1080×1920. Both are built in: pick the preset mode and choose the one you need instead of typing the numbers yourself.
What does 300 DPI mean for an A4 page?
DPI (dots per inch) describes print sharpness: at 300 DPI, an A4 sheet (210×297 mm) needs 2480×3508 pixels to print crisply, which is exactly what the A4 preset produces. Screens do not have a fixed DPI, so this setting only matters when the image is headed to a printer.
Are EXIF data and orientation kept?
Camera metadata itself is not carried into the output, but the orientation it describes is: a portrait photo stored sideways by the camera is straightened before resizing, so the result faces the right way regardless of what your phone recorded.
How many files can I resize at once?
Up to 20 files in one pass with the same settings applied to each, packed into a single ZIP. For folders larger than 20 images, use Bulk Resize Images instead, which is built for hundreds of files at once.
Why do GIF and BMP files come out as PNG?
The browser's Canvas API, which reads these two formats, can only decode them; it cannot write a GIF or BMP back out. PNG is the closest lossless format it can produce, so that is what you get; JPEG, PNG, WebP and AVIF inputs all keep their original format.

- Why Your Compressed JPEG Still Looks BadA photo that looks soft after compressing usually has nothing to do with the compression setting you picked. It is the resolution doing that.
