How to convert HEIC, PNG, WebP, SVG, BMP, and ICO

Drag and drop any supported image into the upload area, or click to browse your device. The tool automatically detects your source format — HEIC from iPhone, SVG vector graphics, BMP bitmaps, GIF animations, PNG, WebP, or JPG.

Choose the output format from the dropdown: JPG for photos and sharing, PNG for lossless graphics with transparency, WebP for modern web performance, BMP for legacy Windows apps, or ICO for favicons and Windows icons (exported at 16×16, 32×32, and 48×48 pixels).

Click "Convert image" to process the file. HEIC and HEIF files are decoded locally with WebAssembly before canvas rendering. SVG files are rasterized in-browser. A progress bar keeps the interface responsive while large images are processed. Your converted file downloads instantly — no account, no cloud, and no server upload.

Frequently asked questions

How to convert iPhone HEIC photos to JPG on browser?

Upload your .heic or .heif file from your iPhone or Mac. The tool decodes HEIC locally in your browser using WebAssembly, then lets you export to JPG, PNG, WebP, BMP, or ICO. No iTunes, no cloud upload, and no third-party app required.

Is it safe to convert my private images here?

Yes. Every conversion runs 100% on your device. Files are never uploaded to a server, stored in the cloud, or shared with anyone. Close the tab and your images are gone from the tool entirely.

Can I convert PNG to WebP or SVG to PNG for free?

Yes. Select PNG to WebP for smaller web assets, or upload an SVG and export PNG for social media, presentations, or apps that do not support vector graphics. All conversions are free with no watermarks.

How do I create an ICO favicon from a JPG or PNG?

Upload your image, choose ICO as the output format, and click Convert. The tool generates a multi-size Windows icon file (16, 32, and 48 px) ready for favicons, desktop shortcuts, or app icons.

Can I convert BMP to JPG or WebP online?

Yes. Upload a BMP file and pick JPG or WebP to reduce file size while keeping visual quality. BMP input and output are both supported entirely in your browser.

Is my data safe with this tool?

Yes. All processing runs 100% on your device using client-side WebAssembly, Canvas API, and browser APIs. No bytes from your files are transmitted to our servers — zero server upload, absolute privacy.

Why is the processing speed so fast?

Because your file never leaves your browser. SnapKit uses WebAssembly and Canvas to harness your device CPU and GPU directly, skipping slow network upload and download steps.
