Bulk Convert Images Online, Free — No File-Count Limit
File Tools Online · July 2026 · 5 min read
Converting one image is trivial. Converting a folder of 60 iPhone photos from HEIC to JPG, or an entire product catalog from PNG to WebP for a faster website, is where most free tools start capping you at 10 or 20 files and asking you to pay for the rest. This one doesn't cap the batch.
Converting Whole Folders at Once
Upload a ZIP of images in any supported format — including iPhone HEIC files that plenty of software still can't open directly — and get back a ZIP of converted images in your target format, all in one pass.
Why WebP Conversion Matters for Websites
WebP images are dramatically smaller than PNG or JPG at equivalent visual quality, which directly improves page load speed and Core Web Vitals scores — a meaningful factor for both user experience and search ranking. Bulk-converting an entire image library to WebP is one of the highest-leverage, lowest-effort website performance fixes available.
