Crop every image accurately
Process a whole folder at once while analysing each PNG individually, so icons, stickers, logos, sprites, and cut-outs are trimmed to their own visible artwork.
Coming soon for macOS
PNG Auto Cropper
Trim transparent padding from a whole folder of PNGs in one pass.
Every image is analysed individually and cropped to the true bounds of its visible content, giving differently shaped assets an accurate result without forcing them into one fixed crop.
Built for batches
Every PNG gets the crop it actually needs.
Fine-tune the result
Add consistent padding to every crop and adjust the alpha threshold to remove faint transparent halos around image edges.
Preview and export safely
Compare original and cropped dimensions before exporting to a separate folder. Originals stay untouched, with collision-safe filenames preventing accidental overwrites.
A simple workflow
From padded assets to tidy exports.
Keep the common path quick, with precise controls ready when an image needs a little more care.
