HEIC to WEBP
Convert HEIC photos to WEBP format for the web in your browser. No upload.

HEIC and HEIF files only. Files never leave your browser.
HEIC to WEBP converts Apple's HEIC photos into WEBP — the modern web image format developed by Google. WEBP delivers smaller file sizes than JPEG at comparable visual quality and is supported by all major browsers and content management systems. This tool is designed for workflows where iPhone or iPad photos need to go directly onto a website, blog, or web application. All processing happens in your browser; no files are uploaded.
Tool interface
The interface includes compression control alongside the standard upload flow:
- A drag-and-drop upload area for HEIC and HEIF files
- A quality slider to control the WEBP output quality
- A file list showing each filename and original size
- Live before/after file size comparison after conversion

Tool description
HEIC to WEBP performs a deliberate two-step conversion. First, the HEIC file is decoded into raw pixel data using a WebAssembly-based HEIC decoder. Second, that raw data is re-encoded as WEBP at the quality level you set via the Canvas API. The intermediate step is lossless — only one lossy compression decision is made, which is the final WEBP export. This avoids the quality loss that would result from a HEIC→JPEG→WEBP chain.
The quality slider controls the WEBP encoder's lossy compression level. Higher quality values preserve more detail at larger file sizes; lower values produce smaller files with more compression artifacts. For most web publishing use cases, 75–85% produces excellent results — noticeably smaller than JPEG while maintaining good visual quality.
Some practical use cases:
- Converting iPhone photos before uploading to a WordPress, Shopify, or Webflow site
- Preparing product images from a phone shoot for an e-commerce page
- Optimising travel or event photos for a portfolio website
- Batch-converting a set of HEIC images for a web project
How to use
- Drop your HEIC or HEIF files onto the upload area, or click
Browseto select them. - Adjust the quality slider — 80% is a good starting point for web use.
- Click
Convert & Downloadto begin conversion. - The tool decodes HEIC first, then re-encodes as WEBP — allow a few seconds per file.
- Single files download as
.webp; multiple files are packaged as a ZIP archive.
FAQ
Why convert to WEBP instead of JPG?
WEBP typically achieves 25–35% smaller file sizes than JPEG at equivalent perceptual quality. Smaller images mean faster page loads, lower bandwidth use, and better Lighthouse/Core Web Vitals scores. All major browsers have supported WEBP since 2020.
Does the two-step conversion reduce quality?
No. The intermediate step between HEIC decoding and WEBP encoding passes lossless raw pixel data through the Canvas API. Only one lossy compression is applied — the final WEBP encoding at your chosen quality level.
Can I convert multiple HEIC files at once?
Yes. Select or drop multiple files and all of them are converted. The WEBP outputs are downloaded as a single ZIP archive.
Are my photos uploaded anywhere?
No. Both the HEIC decoding and the WEBP encoding run entirely in your browser. Your files are never transmitted to any server.
What quality setting should I use?
75–85% covers most web publishing needs. Use higher values (90%+) if the images will be displayed at large sizes or used as hero images. Use lower values if minimising file size is the priority on data-sensitive pages.
Is WEBP supported everywhere?
WEBP is supported by all major browsers (Chrome, Firefox, Safari, Edge) and most modern CMS platforms. For very old browsers or email clients, JPG remains the safer universal choice.
