Add your SRW file
Drop one or more .srw files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.

Developing a .srw camera file into .webp turns unprocessed sensor data into a finished image any app can open. An .srw file is a Samsung RAW photograph from the company's NX-series mirrorless cameras and a few compacts, produced only during Samsung's 2010-2015 push into dedicated cameras. Because Samsung exited the camera business, .srw is now an orphaned format: existing files remain readable, but no new cameras will ever create them.
A .webp file is Google's web-oriented image format, offering both lossy and lossless compression plus alpha and animation in one container. At equivalent visual quality, .webp files typically undercut JPEG by 25-35 percent, which is why CDNs and site optimizers convert to it aggressively. For this route the practical draw is smaller than JPEG for photos and usually smaller than PNG for graphics and one format covers lossy, lossless, alpha, and animation — balanced against mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF, which is worth knowing before you commit a large batch.
Why convert SRW to WEBP?
The practical trigger for this conversion is usually a mismatch: with .srw, the format is abandoned: no vendor updates, no new hardware, dwindling attention. Switching to .webp buys you smaller than JPEG for photos and usually smaller than PNG for graphics, which is why it is the better fit for serving photos and graphics on websites where bandwidth and Core Web Vitals matter. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
SRW vs WEBP at a glance
| Aspect | Samsung RAW (.srw) | WebP image (.webp) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossy — discards detail it judges invisible to shrink files |
| How it stores data | tIFF-based container with Samsung-specific tags around 12- and 14-bit Bayer mosaic data | lossy mode encodes VP8 intra frames with block prediction; lossless mode uses its own dedicated coding with spatial predictors and color transforms |
| Strongest at | reprocessing photo libraries shot on NX-system cameras | serving photos and graphics on websites where bandwidth and Core Web Vitals matter |
| Weak spot | the format is abandoned: no vendor updates, no new hardware, dwindling attention | mandatory 4:2:0 subsampling in lossy mode caps color fidelity below high-quality JPEG or AVIF |
| Metadata | standard EXIF and Samsung MakerNotes are embedded and still parsed correctly by ExifTool and major raw engines; XMP lives in sidecars written by editors | eXIF and XMP travel in dedicated RIFF chunks and ICC profiles are supported, though a fair amount of conversion software strips metadata by default when writing WebP |
Pick WEBP as the output
Select .webp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WEBP is selectable, the route is real and validated.
Convert on your device
Press Convert. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WEBP file. Outputs keep the original filename with the .webp extension.
SRW to WEBP questions, answered
Will converting SRW to WEBP lose quality?
Some. Since srw is lossless-oriented and webp is lossy-oriented, the encoder will discard detail it judges least visible; the quality slider controls how aggressive that is. Keep the original .srw if you may need a pristine master later.
Is it private to convert SRW files here?
Yes — the .srw file is processed inside your browser tab and never uploaded. A LibRaw WebAssembly decoder demosaics the sensor data in your browser and renders a developed image ready for export. Close the tab and the file is gone from memory.
Where will the WEBP file work?
Chrome, Edge, Firefox, and Safari (since version 14 in 2020) all decode WebP natively, as do Android and current versions of Windows and macOS system viewers. Older tools from before roughly 2020 — legacy Photoshop releases, older email clients, many kiosk printers — commonly fail on it, so JPEG or PNG remains the safer handoff format outside the browser.
Will the WEBP file be bigger or smaller than my SRW?
Smaller, usually dramatically so — that is the main reason this route exists. The quality slider trades size against fidelity; the default sits at the point where most people cannot spot the difference.
What happens to the metadata in my SRW file?
In .srw, standard EXIF and Samsung MakerNotes are embedded and still parsed correctly by ExifTool and major raw engines; XMP lives in sidecars written by editors. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
