What does a bulk image converter do?
A bulk image converter switches lots of photos to a new file format in one pass, so HEIC, PNG, JPG and WebP files all come out in whichever single format you need. Forget opening each picture in an editing app and saving it out by hand: drag in a whole folder, pick one output format and download all the converted images together as a ZIP. The work happens locally, so you can convert even a big batch of high-resolution photos in seconds without uploading anything.
Wrong-format files cause trouble all the time. iPhones save pictures as HEIC, which many marketplaces and apps will not open; websites get faster when you convert their images to WebP; and logos keep their transparent background only as PNG. This free online converter covers every one of those situations: choose your images, select a target format, set the quality and let the tool convert the full set. Nothing to install, no account, no nasty quality surprises — just consistent images ready to publish. Since it processes whole batches, a chore that once meant exporting files individually turns into one drag, one click and one download, whether you convert five screenshots or five hundred product shots.

How to get image conversion right
Convert once and use the files anywhere.
HEIC → JPG for maximum compatibility
Every platform takes JPG — convert HEIC to JPG before uploading to a marketplace, web form or CMS.

Images going onto a website? Convert them to WebP for lighter files with no visible drop in quality.
PNG only when you need transparency
Only convert to PNG when a transparent background is essential — JPG or WebP will be lighter otherwise.
Bulk image converter questions
Is it genuinely free?
Yes. You pay nothing, skip the sign-up, never see a watermark, and there is no cap on how many images the bulk image converter will convert.
Do my images get uploaded somewhere?
No. All of it runs right inside the browser on your machine, so no server ever receives your images and they never leave your computer.
Can HEIC be converted to JPG?
Yes — Apple's HEIC files are decoded inside your browser and converted to JPG, PNG or WebP, so photos from your iPhone open anywhere.
Which formats can I convert?
Load HEIC, JPG, PNG or WebP files, pick one target — JPG, PNG or WebP — and convert every file in the batch: HEIC to JPG, for example, or PNG to WebP.
Will the file size change after converting?
Usually. JPG or PNG photos converted to WebP tend to get lighter, whereas PNG output grows larger but loses nothing.
Will converting lower the quality?
Pick a lossy target (JPG or WebP) and the quality level you set is applied; PNG output is always lossless. Between 80 and 90, most pictures look no different from the original.
Can I resize during conversion?
Yes — turn on the max-size setting to limit the longest side as you convert, and you will end up with even lighter files.
What is the point of converting to WebP?
At equal quality WebP files are about 25–35% lighter than JPG, so pages load quicker and Core Web Vitals improve.
Can I convert AVIF files?
You can convert AVIF files wherever your browser can read them; the output will be JPG, PNG or WebP.
Is there anything to install?
No. The bulk image converter works in any current browser — no software, no extension, no account.
