ImageConverter is a free, browser-based image conversion tool that lets you convert SVG, HEIC, AVIF, TIFF, GIF, JPEG, JPG, PNG, and WebP files without uploading to any server.
What is ImageConverter?
ImageConverter is a browser-native image format converter that runs entirely client-side. It accepts image uploads via drag-and-drop or file selection and produces converted files in a chosen output format (JPG, PNG, WebP, and others). The tool is hosted at imageconverter.dev and processes all data locally using Web APIs, meaning files never leave your device.
Key Features
- 100% browser-based processing — All conversion happens locally; no server uploads, no tracking, no account required. After the page loads, the converter works even offline.
- Wide format support — Handles modern and legacy formats: SVG, HEIC, AVIF, TIFF, GIF, JPEG, JPG, PNG, and WebP. Maximum file size is 50MB per image.
- One-click conversion presets — Dedicated shortcut links for common conversions: PNG to JPG, JPG to PNG, WebP to PNG, SVG to WebP, HEIC to JPG, AVIF to PNG, TIFF to WebP, and many more.
- Output quality control — Adjust compression quality (for JPG and WebP outputs) and preview the resulting file size before downloading.
- Drag-and-drop interface — Drag an image file directly into the workspace; source format is detected automatically.
- Free, unlimited, watermark-free — Convert as many files as you want with no sign-ups, quotas, or watermarks.
- Extra in-browser tools — The same site also offers a watermark remover, free image compressor, free image resizer, and bulk resize tool, all processing locally.
Who is it for?
- Web developers and designers — Convert icons and graphics from SVG to PNG or WebP for web-ready assets without leaving the browser.
- Photographers and content creators — Batch convert HEIC or TIFF photos to JPG for broader compatibility, or compress images for email and social sharing.
- Anyone handling mixed-format image sets — Quickly flip between GIF, PNG, and JPEG without installing desktop software or worrying about privacy.
What can you do with ImageConverter?
- Convert for web publishing: Transform large HEIC/AVIF files to WebP or PNG to reduce page load times while preserving transparency (converted to white background when exporting to JPG).
- Remove watermarks locally: Use the built-in reverse-alpha-blending tool to erase solid-color watermarks without server uploads.
- Batch resize multiple files: Resize entire image collections to custom dimensions in JPG, PNG, or WebP, all in your browser.
How does ImageConverter work?
- Select or drop an image – Upload a file or drag it onto the workspace. The tool automatically detects the source format.
- Pick output settings – Choose a target format and, for JPG or WebP, adjust the quality slider.
- Download instantly – The converted file is ready for immediate download. No queues, no uploads, no tracking.

FAQ
Is ImageConverter free to use?
Yes. Every converter on imageconverter.dev is free, unlimited, and watermark-free. You can convert as many files as you want without creating an account.
Do my images ever upload to a server?
No. All conversions happen entirely in your browser using Web APIs. After the page loads, you can even go offline and the converter will continue working.
Will the converter reduce image quality?
Image resolution is preserved. Gentle compression is applied only when the target format requires it. Transparent backgrounds are automatically flattened to white when exporting to JPG.
