Before you begin

Choose a non-interlaced 8-bit RGB/RGBA PNG, up to 10 MiB, 20 million pixels and 8192 pixels per side. Animation, EXIF, ICC profiles and compressed/international text metadata are unsupported. Output is limited to 20 MiB. One operation runs at a time.

Check your result

Keep proportions on to avoid stretching. Turn it off only when independent dimensions are intended. No automatic crop is applied. Inspect the downloaded file before sharing it or replacing an original.

Selected files stay in this browser. No image bytes are uploaded by this tool. Clearing releases tool references, which is not a secure-erasure promise. Browser memory or encoder support can impose lower limits.
