Free bulk image conversion without the usual catches
Most online converters cap you at 10 or 20 files, add a watermark, or ask for an account before letting you download. This bulk image converter has none of that. Select or drag in as many JPG, PNG, WebP or HEIC files as your device can hold, choose the output format and quality, click Convert all, and download each file or everything in one ZIP. Because the conversion runs inside your browser, there is no upload queue, no server limit and no waiting for an email link.
How to batch convert images
- Drop your files or click the box to select them; folders of hundreds of photos are fine.
- Type the output format: jpg for the smallest files and universal support, png for lossless graphics and transparency, webp for websites.
- Set quality (85 is a safe default; 70 for maximum compression).
- Click Convert all, then Download all (ZIP).
Privacy and performance
Your images never leave your device, which makes this safe for ID documents, client photos and anything confidential. Speed depends on your computer rather than our server: a modern laptop converts roughly 100 phone photos a minute. On mobile, batches of 50–100 work well; very large batches may need to be split.
Common bulk conversion jobs
Converting a wedding album from HEIC to JPG for relatives on Android, compressing 300 product photos to WebP before uploading to a Shopify or WordPress store, turning PNG screenshots into JPG for a presentation, or standardising a mixed folder to one format before archiving.
Frequently asked questions
Is there really no file limit?
None set by us. The only limit is your device's memory; hundreds of photos at a time is normal on a laptop.
Do I need to create an account?
No. There is no sign-up, no email and no watermark.
Are my photos uploaded to your server?
No. Conversion happens in your browser using the Canvas API; you can even disconnect from the internet after the page loads.
Can I convert HEIC files in bulk?
Yes. iPhone HEIC and HEIF photos are decoded on your device and converted like any other image.
Does it keep image quality?
PNG output is lossless. JPG and WebP use the quality you set; 85–90 is visually identical for photos.
