What it does
WtConvert came out of needing to resize hundreds of product photos every week without paying for Photoshop. Drop a folder in, set the output dimensions and format, and it handles the rest. No quality loss when converting between lossless formats, and you get sensible compression defaults for lossy ones.
It supports everything: JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF, GIF. The watermarking tool lets you stamp text or a logo image on every file in a batch.
