People Also Use
Turn your HEIC images into WebP right in the browser — this tool will grow each file and hand it back in seconds, with nothing uploaded to any server. HEIC is Apple's high-efficiency format, storing iPhone photos at roughly half the size of JPEG with better quality. WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. The conversion keeps your image faithful while switching it into the WebP container. Free, private, unlimited, and watermark-free.
How to Convert HEIC to WebP
Add your HEIC files
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to WebP
Pick a quality level if you want to trade a little detail for a smaller file, then press Convert. Encoding is instant for most images.
Download
Save each WebP file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert HEIC to WebP?
The main reason is web images where small size matters, with transparency and animation supported in one format. HEIC excels at iPhone photos, but when you need smaller, widely-supported files, WebP is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
Converting into WebP re-encodes the image, and because WebP is lossy you control the trade-off with the quality setting. At high quality the difference is invisible.
A note on file size
File size will be broadly similar to your original HEIC.
About HEIC
HEIC is Apple's high-efficiency format, storing iPhone photos at roughly half the size of JPEG with better quality. Best for iPhone photos, where it saves storage dramatically over JPEG.
About WebP
WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. Best for web images where small size matters, with transparency and animation supported in one format.
Common Uses for HEIC to WebP
- Converting HEIC to WebP for a project that specifically requires WebP files, where HEIC is not accepted.
- Preparing images for the web, where WebP keeps file sizes small and pages fast.
- Batch-converting a whole folder of HEIC images to WebP at once, instead of doing them one at a time.
- Switching a High Efficiency Image Container export into WebP so it opens correctly in the tools your team actually uses.
- Compressing large HEIC images into smaller WebP files to save storage and bandwidth.

Tips & Things to Know
Check the file size after converting
File size will be broadly similar to your original HEIC. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your HEIC stay transparent in the WebP — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your HEIC files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
Tune the quality if you need to
For WebP you can trade a little detail for a smaller file using the quality slider. At around 90% the difference is invisible to the eye, while the file can be much smaller — useful for web images and email attachments.
Frequently Asked Questions
How do I convert HEIC to WebP for free?
Add your HEIC file above and press Convert. The WebP download appears in seconds. It is completely free, with no signup, no limits and no watermark.
Is my HEIC uploaded to a server?
No. The entire conversion runs inside your browser using your device's own processor, so your images never leave your computer. That matters for private photos and confidential work.
Can I convert multiple HEIC files at once?
Yes. Add as many as you like and they are converted in one batch, then offered individually or as a single ZIP download.
Will converting to WebP reduce quality?
Only if you choose a lower quality setting. At high quality the result is visually identical to the original.
Does WebP support transparency?
Yes, WebP supports an alpha channel, so transparent areas in your image are preserved.
Why is my WebP file larger than the HEIC?
WebP stores 24-bit colour with optional alpha, so it is naturally larger than HEIC. This is expected and the image quality is fully intact.
What is the difference between HEIC and WebP?
HEIC is Apple's high-efficiency format, storing iPhone photos at roughly half the size of JPEG with better quality. WebP is Google's modern format that does both lossy and lossless, typically 25–35% smaller than JPEG or PNG at the same quality. That difference is what this conversion is really about.
Is there a file size limit?
Because processing happens in your browser, very large images depend on your device's memory, but typical photos convert instantly. Nothing is capped by an upload limit.
Do I need to install anything?
No. This works in any modern browser on any device — Windows, Mac, Android or iPhone — with nothing to install.
Is this HEIC to WebP converter really free?
Completely free, forever, with no account, no watermark and no hidden premium wall.
