Free Online Image Format Converters
Image format conversion comes up constantly — an iPhone photo in HEIC that won't open on Windows, a PNG that's too large to email, a JPG that needs transparency, a WebP that won't open in an older app. The right format depends on what you're doing with the image, and switching between them should take seconds.
All 11 converters on this page run entirely in your browser. Your images are processed using the Canvas API and WebAssembly — no file is ever transmitted to a server. That means conversions are instant (no waiting for uploads and downloads), work offline, and keep your photos private. There are no file size limits beyond your device's available memory.
Whether you need a single format conversion or a more complex workflow — like converting RAW files from a camera shoot, stripping HEIC photos from an iPhone backup, or preparing images for web deployment — you'll find the right tool below.
Format Conversion Quick Reference
Choosing the right output format is just as important as converting. Here's a quick overview of each format's characteristics and ideal use cases.
| Format | Characteristics | Best For |
|---|---|---|
| JPG / JPEG | Universal, lossy compression, smallest file size for photos | Photography, email, social media |
| PNG | Lossless, supports transparency, larger files | Logos, graphics, screenshots, design assets |
| WebP | Modern, smaller than JPG and PNG, supports transparency | Web images, page performance, modern apps |
| HEIC | iPhone default, excellent quality at small size, limited compatibility | iOS camera output — convert before sharing |
| SVG | Vector-based, infinite scalability, resolution-independent | Logos, icons, illustrations, UI graphics |
| RAW | Unprocessed camera data, maximum editing latitude | Professional photography, post-processing |
| AVIF | Next-gen compression, smallest files, growing browser support | Modern websites, Core Web Vitals optimization |
| BMP / TIFF | Uncompressed or lossless, very large files, limited web support | Scans and print — convert to JPG for sharing |

Which Format Should You Use?
The best format depends on your specific use case. Here's a practical guide to making the right choice.
Use WebP for websites
WebP is the optimal format for web images in 2024. It produces files 25–35% smaller than JPG and up to 60% smaller than PNG, while supporting transparency and animation. All major browsers have full WebP support. Converting your site's images to WebP is one of the highest-impact performance improvements you can make.
Use JPG for photos and sharing
JPG (JPEG) remains the universal format for photographic images. Every operating system, messaging app, social platform, and email client handles JPG flawlessly. For photos you're sharing, emailing, or printing, JPG is the safest choice. Use a quality setting of 80–85% for an excellent balance of size and appearance.
Use PNG for graphics with transparency
PNG is the standard for images that require a transparent background — logos, UI elements, icons, and product images on colored backgrounds. Unlike JPG, PNG uses lossless compression, so fine text and sharp edges are preserved perfectly. For web use, consider converting to WebP (which also supports transparency) to reduce file size.
Use SVG for logos and icons
SVG is the right format for logos, icons, illustrations, and any graphic that needs to look sharp at every size. Unlike raster formats, SVG scales infinitely without pixelation. SVG files are also tiny compared to high-resolution PNG equivalents, and they can be styled with CSS and animated. If your designer handed you a PNG logo, ask for the SVG source — or use our PNG to SVG converter for simple graphics.
A note on HEIC and RAW
HEIC is Apple's default camera format — it produces excellent quality at roughly half the file size of JPG. The problem is compatibility: Windows, Android, and most web platforms don't support HEIC without additional software. The solution is simple: convert to JPG before sharing. RAW files from cameras contain the full unprocessed sensor data, giving photographers maximum flexibility in post-processing. They're large and not meant for sharing — convert to JPG after editing.
Frequently Asked Questions
Do my images get uploaded to a server when I convert them?
No. Every converter on this page runs entirely in your browser using the Canvas API, WebAssembly, and browser-native libraries. Your image data is processed in local memory and never transmitted to any server. You can verify this by opening your browser's network inspector — no upload request will appear.
Which format should I choose for website images?
WebP is the best choice for websites in 2024. It produces files 25–35% smaller than equivalent JPG images and 50–60% smaller than PNG, while supporting both lossy (photo) and lossless (graphic) compression. All major browsers have supported WebP since 2020. Use PNG as a fallback only for very old browser support requirements.
Why can't I open HEIC photos on Windows or Android?
HEIC is Apple's proprietary format based on the HEIF standard. Windows requires a paid codec extension from the Microsoft Store to open HEIC files, and most Android apps don't support HEIC natively. The simplest fix is to convert HEIC to JPG before sharing — our HEIC to JPG converter does this instantly in your browser.
Does converting between formats reduce image quality?
It depends on the conversion. Lossy-to-lossy conversions (like WebP to JPG) do introduce a small amount of quality loss with each conversion — called generation loss. Lossless-to-lossy conversions (PNG to JPG) permanently discard some data. Lossless-to-lossless conversions (PNG to WebP lossless) preserve all quality. For best results, always convert from your original source file rather than a previously converted copy.
Can I convert RAW photos from any camera brand?
Yes. The RAW to JPG converter supports the most common proprietary RAW formats: CR2 and CR3 (Canon), NEF (Nikon), ARW and SRF (Sony), DNG (Adobe universal), RW2 (Panasonic), ORF (Olympus), and PEF (Pentax). DNG files produced by Adobe Lightroom and many mirrorless cameras are universally supported.
What's the difference between PNG to SVG and a regular image converter?
SVG is a vector format, while PNG is raster (pixel-based). Converting PNG to SVG involves a process called image tracing or vectorization — the converter analyzes the pixel boundaries and generates mathematical path descriptions. This works well for logos, icons, and simple illustrations with clear edges. It doesn't work well for photographs because the resulting SVG would have an enormous file size with thousands of traced shapes.
