Batch Image Converter
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.

Frequently Asked Questions
How is this different from Bulk Image Converter?
This tool converts mixed input folders to ONE chosen output format per batch — fastest for uniform jobs. Bulk Image Converter offers 100+ dedicated format-pair pages with per-pair tuning. Redesigning 150 mixed images to WebP: use this; converting PNG→AVIF specifically: use that pair page.
What output format fits a site redesign?
WebP quality 80 for photos (modern browsers, ~30% smaller than JPEG), PNG for graphics with text. Only JPG, PNG, and WebP outputs exist — convert the full set in one batch, then spot-check a few downloads.
Do folder structure and names survive?
No — the ZIP is flat with no directory layout: each file keeps its basename with the new extension (image_0, image_1 fallback when a name has no stem). Rebuild your upload paths after downloading.
Does batch conversion upload images?
No — conversion runs locally in your browser; images never leave your device. Only the final ZIP counts as one Pro download (signed-in free: 2 a day).
