About the output
All decoding, resizing and ZIP creation run in your browser. This tool does not upload, log or store your images or filenames. Reset, cancel or leave the page to release them.
Exports are still images with metadata removed. Browser decoding and sRGB output can change HDR or wide-gamut colors. Enlarging cannot restore detail, and the output may be larger than the source.

Frequently asked questions
Are these official platform requirements?
No. Square (1080 × 1080), Portrait (1080 × 1350), Story (1080 × 1920), and Landscape (1200 × 630) are named pixel presets. They do not guarantee acceptance or prevent a platform from cropping or recompressing the image. Use custom dimensions for your particular destination.
How do crop and contain differ?
Crop to fill covers every output pixel, trimming the edges as needed. Contain keeps the full image and adds spare space around it. Placement runs from left to right and top to bottom across the available crop or spare space. Settings apply to all selected sizes. Change settings and create images again to update the results.
Which formats and transparency are supported?
The browser tries to decode the file regardless of its extension. PNG, JPEG and WebP are common inputs; other formats depend on the browser. Animated inputs become one still frame. PNG and WebP can preserve transparent pixels; JPEG always uses the selected background color. PNG is lossless; the quality slider controls lossy JPEG and WebP encoding.
Is there a size limit?
There is no chosen file or pixel cap. Output dimensions must be positive whole numbers. Available device memory and browser canvas capabilities determine what can finish; use Cancel & clear to stop a job. ZIP downloads use ZIP32, whose file-count and roughly 4 GiB archive bounds may prevent an archive; completed individual downloads remain available.
Do previews match downloads?
Result cards show the exact encoded output files scaled down for display. Transparent areas use a checkerboard only on this page. Changing a resize setting clears old results to avoid downloading an outdated version. Download filenames include the size and dimensions.
