Use the free Photo to Web →How to convert RAW to JPEG in your browser
Photo to Web runs the full RAW-to-JPEG pipeline — demosaic, color transform, resize, JPEG encode — entirely in your browser tab. This is what makes it a true RAW to JPEG converter with no server: the compute happens on your device, not on a remote machine. Convert camera RAW to web JPEG without ever leaving your tab.
- Open capsuletools.app/photo-to-web/
- Tap the zone (on iPhone) or drag your photo onto it (on desktop)
- The browser decodes the file, shows a preview, and provides
[filename]-web.jpgfor saving
On first use with a RAW or HEIC file, you'll briefly see a "Loading decoder…" message while the WebAssembly module initializes. After that, conversions are instant.
Supported formats: DNG, HEIC, JPEG, PNG, and more
Photo to Web accepts any image format your browser can pick from the Files or Photos app. DNG to JPEG online free is the primary use case, but the tool handles every major format automatically:
- DNG
- CR2
- CR3
- NEF
- ARW
- RAF
- ORF
- RW2
- PEF
- SRW
- 3FR
- DCR
- HEIC
- HEIF
- JPEG
- PNG
- WebP
- AVIF
- GIF
For HEIC and HEIF, the decoder works without uploading — so you can convert HEIC to JPEG without uploading it to any third-party server. For RAW formats, the tool uses a WebAssembly build of LibRaw, the same engine behind professional desktop software. On an iPhone, pick your DNG directly from the Files app to complete the iPhone DNG to JPEG browser conversion without leaving Safari.
iPhone ProRAW and HEIC — handled automatically
iPhone ProRAW files are DNG files. Photo to Web is the only browser-based ProRAW to JPEG converter that decodes DNG natively on the device — no upload to a third-party API, no desktop app required.
The iPhone DNG to JPEG browser flow: open the tool in Safari, tap the zone, select your ProRAW photo from the Files app (it appears as a .dng), then save the converted image from the preview or tap Download. The resulting JPEG is 1000px on the long edge, suitable for web sharing, email, and any platform with a file size limit.
Resize photo for web, no upload
By default, the output is 1000px on the long edge at 85% JPEG quality — the standard web-share size. To resize photo for web, no upload required at a different size, tap Settings below the drop zone before converting. You can set any max dimension (200–8000px) and quality level (60–95%). These settings persist for subsequent conversions in the same session.
Frequently asked questions
How do I convert DNG to JPG online free?
Open Photo to Web, tap or drag your DNG file, and the browser converts it to JPG instantly — no upload, no account. The decoder runs inside your browser using WebAssembly, so your file never leaves your device and there is no file size limit imposed by a server.
How do I convert RAW photos to JPEG on iPhone?
Open Photo to Web in Safari on your iPhone, tap the zone, and pick your ProRAW or DNG file from the Files app. The tool converts raw photos to JPEG on iPhone entirely in Safari — no app to install, no upload. Tap Download when the preview appears to save the JPG to your device.
Can I convert HEIC to JPG without uploading it?
Yes. Photo to Web is a HEIC to JPG converter with no upload — the decoder runs client-side. Tap to pick your HEIC photo, then use the Download button to save the converted JPG directly to your device. The file is never sent to any server.
Is there a RAW to JPEG converter that doesn't send files to a server?
Photo to Web is that converter. The entire conversion pipeline — RAW decode, resize, JPEG encode — runs in your browser tab. The file is never transmitted anywhere, and there's no network activity after the page loads.
Can I convert a DNG file to JPG on iPhone in my browser?
Yes. Photo to Web works in Safari on iPhone and iPad. Tap the zone, pick your DNG from the Files app, then tap Download when the converted JPG is ready. It uses WebAssembly to run LibRaw natively in Safari — the same library behind professional desktop RAW editors.
How do I resize images for web online without uploading them?
Photo to Web resizes to 1000px on the long edge by default — the simplest way to resize images for web online without uploading anything. Tap Settings below the drop zone and enter a different max dimension for a custom size. The aspect ratio is always preserved.
What's the difference between this and Squoosh?
Squoosh is excellent for compressing images that are already in a browser-readable format. It cannot decode camera RAW formats like DNG, CR2, NEF, or ARW at all. Photo to Web is built specifically to convert camera RAW to web JPEG — it ingests raw sensor data, processes it, and produces a sized JPEG in one step. If your source is a RAW file, Squoosh is not an option; this tool is.
Which camera RAW formats does this convert to JPG?
Photo to Web is a raw file converter online that handles any format supported by LibRaw: DNG, CR2, CR3, NEF, ARW, RAF, ORF, RW2, PEF, SRW, 3FR, DCR, K25, KDC, and more. HEIC and HEIF are also supported via a separate decoder. Standard web formats (JPEG, PNG, WebP, AVIF, GIF) work natively via the browser.
