Convert RAW Photo to JPEG Online — No Upload
Photo to Web is a free browser tool that converts any photo to a web-ready JPEG — instantly, with no upload. Drop a RAW file from your iPhone ProRAW camera, a HEIC from any Apple device, or any other image format, and get back a 1000px JPEG that works everywhere. No server ever sees your file. The entire conversion runs in your browser using WebAssembly.

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 and downloads
[filename]-web.jpgautomatically
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), and the download fires automatically. 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
Can I convert DNG to JPEG online for free without uploading?
Yes. Photo to Web converts DNG to JPEG online free, and your file never leaves your device. The decoder runs inside your browser using WebAssembly — there is no server, no upload, and no file size limit imposed by the tool.
How do I convert iPhone ProRAW to JPEG?
Open Photo to Web, tap the zone, and pick your ProRAW DNG file from the Files or Photos app on your iPhone. The tool decodes it in your browser and downloads a web-ready JPEG automatically. No app install, no desktop, no account needed.
How do I convert HEIC to JPEG without uploading it to a server?
Photo to Web converts HEIC to JPEG without uploading the file anywhere. The HEIC decoder runs client-side. Tap to pick your HEIC photo and the converted JPEG downloads directly to your device within seconds.
Is there a RAW to JPEG converter that doesn't send files to a server?
Photo to Web is that converter. It's a RAW to JPEG converter with no server involved. 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 JPEG in my browser on iPhone?
Yes. Photo to Web works in Safari on iPhone and iPad. Tap the zone, pick your DNG from the Files app, and the converted JPEG downloads. The iPhone DNG to JPEG browser conversion uses WebAssembly to run LibRaw natively in Safari — the same library used in desktop RAW editors.
How do I resize a photo for the web without uploading it?
Photo to Web resizes to 1000px on the long edge by default — the simplest way to resize photo for web, no upload needed. 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 JPEG?
Photo to Web converts camera RAW to web JPEG from 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.
