HEIC to WebP Converter

.heic → .webp (High Efficiency Image Container → WebP, lossy)

.heic → .webp

Convert High Efficiency Image Container images to WebP entirely in your browser. The source file is decoded with the browser’s native image pipeline, rendered to a canvas, and re-encoded in the target format. Nothing is uploaded — Convertitive cannot see, log, or store the image you drop in. WebP is lossy, so you can trade visual fidelity for file size with the quality slider — 92% is the default and usually visually indistinguishable from the original.

Conversion happens entirely in your browser. Your file never leaves this page.

How to convert High Efficiency Image Container to WebP

  1. Drop or pick your image

    Drag a .heic file onto the upload box, or click to choose one from your device. Up to 25 MB.

  2. Pick WebP as the target

    WebP is already selected. Adjust the quality slider if you want smaller files at the cost of some fidelity.

  3. Click Convert and download

    The browser renders your image onto a canvas and re-encodes it as WebP. The download button appears the moment the file is ready.

Frequently asked questions

How do I convert HEIC to WebP?
Drag your .heic file into the upload box, leave WebP selected, then click Convert. The download button appears as soon as the new file is encoded.
Is the conversion lossy?
Yes. WebP is a lossy format — pixels are approximated to save space. You can raise the quality slider toward 100% to minimize the loss.
What happens to transparency?
Transparency is preserved end-to-end as long as both formats support it. WebP does support transparency.
Is my file uploaded anywhere?
No. Everything runs in your browser — the file never leaves your device. Convertitive cannot see, log, or store it.
What's the maximum file size?
25 MB. Larger images won't open here because the browser keeps them fully in memory. For very large photos, downsample first.
Will my image be resized?
No. The output has the exact same pixel dimensions as the source. Only the encoding changes.
Why is the output sometimes larger than the input?
Re-encoding does not always make a file smaller — the source image may already be near-optimal for its format. Try a lower quality setting if file size matters.
Which browser do I need?
Any browser released since 2020 supports all three formats. AVIF is not in the picker yet; we'll add it once Safari ships full encoder support.

About HEIC and WebP

HEIC .heic

HEIC is Apple's default photo format on iPhone since iOS 11 — roughly half the file size of an equivalent JPEG at the same visual quality. Most non-Apple software and every web browser can't open it directly, which is why photos AirDropped or emailed from an iPhone often show up as a blank or broken file. Convertitive decodes HEIC locally in your browser and re-encodes it as JPG or PNG — nothing is uploaded.

WebP .webp

WebP is a modern format from Google that supports both lossy and lossless compression plus full transparency. It produces files roughly 25–35% smaller than JPEG at the same quality, and smaller than PNG for most graphics. Browser support is universal on every modern browser since 2020.
