App Store Screenshot Resizer

Fit scales the image until every part is inside the target canvas. If the source and target have different proportions, background appears around the image. Fill scales until the entire canvas is covered, which can remove content from the sides or the top and bottom. Neither mode changes the relative proportions of the app interface.

Choose based on the information you need to preserve. Fit is useful when every control matters. Fill can work when the source has nonessential margins, but inspect the output carefully. A crop that removes a button or cuts a meaningful line of text may change what the screenshot communicates. The tool uses a centered crop and does not let you move the crop position.

Choose a supported iPhone or iPad preset from the selector. Portrait uses the dimensions shown there; landscape reverses width and height. Output is produced at that exact canvas size, with no extra export-scale multiplier. The filenames include the dimensions so you can identify the target after downloading a batch.

Resizing is not layout adaptation. An iPhone capture remains an iPhone interface even if you select an iPad target. The tool cannot reposition text that has already been baked into the source image or recover detail lost in an earlier export. When the composition needs structural changes, return to the editable source document in the studio.

Upload up to eight PNG, JPEG or WebP images, each up to 20 MB and no more than 80 MB total. Choose one target and orientation for the batch, select Fit or Fill, then generate the results. Processing happens one image at a time. Download individual results or one ZIP, with numbered filenames preserving the selection order.

A larger output does not create new detail. Low-resolution source text can look soft when enlarged, even if the final dimensions are correct. Open the result and inspect the smallest meaningful text before uploading it. For a different target, change the selector and regenerate; previous results are cleared so an old-size file is not confused with the new settings.

JPEG downloads contain no alpha channel. PNG downloads are encoded as RGB PNG files without alpha rather than as default browser RGBA PNG files. The selected artwork background fills exposed canvas areas, and any remaining transparent pixels are flattened during encoding. This handles file structure separately from how solid an image looks in a preview.

After resizing, run the downloaded file through the screenshot checker. That lets you verify the dimensions and PNG metadata of the actual output, not the original source. File checks do not assess screenshot content or guarantee acceptance. Keep a copy of the original image so you can compare cropping and avoid repeating lossy JPEG conversions unnecessarily.
