CRW Converter

How to Convert CRW to Any Format

1. Upload Your CRW File: Drag and drop your Canon raw file or click "Add Files". The hub accepts .crw (Canon Raw version 1) and processes the camera's raw sensor data into a finished image. Batch is supported — drop in a folder of CRWs from an old EOS shoot and each one converts in parallel.
2. Pick an Output Format and Quality Preset: Choose the target from the Image File Extension dropdown — JPG, PNG, TIFF, WebP, AVIF, HEIC, BMP, GIF, PPM, or PDF. The default Quality Preset is "Very High (Recommended)"; drop it to Medium or Low to shrink JPG/WebP output, or set Image Quality (%) for a precise compression level.
3. Set Bit Depth, Lossless, or Resolution (Optional): For an archival or edit master, pick TIFF or PNG and set Bit Depth to "16-bit (High Precision)" to preserve the wide tonal range of the raw capture; flip the "Lossless?" toggle to "Yes" for PNG/WebP. Under Image resolution, keep original or pick a Preset Resolution to downscale.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Popular CRW Conversions

• CRW to JPG — the everyday choice: a small, universally viewable photo you can share, email, or print
• CRW to PNG — lossless output when you want no JPEG artifacts, ideal for crops and edits
• CRW to TIFF — a 16-bit archival master that editors and print labs accept
• CRW to WebP — modern web delivery, smaller than JPG at the same quality
• CRW to PDF — wrap one or several CRW frames into a single shareable document

Why Convert a CRW File?

CRW is Canon Raw version 1 — the company's original digital raw format, written in the Camera Image File Format (CIFF) container that Canon released in 1997. It carries the unprocessed 12-bit sensor readout from a handful of early Canon bodies made roughly between 2000 and 2004: the EOS D30, D60, and 10D, the Digital Rebel (300D), and PowerShot models like the G1–G6, S30–S70, and Pro1. In 2004 Canon replaced CRW with the TIFF-based CR2 format (starting with the EOS-1D Mark II), and CIFF was never adopted by anyone but Canon — which is exactly why CRW compatibility is so poor today.

That orphaned-format problem is the whole reason people convert CRW. A raw file is not a picture; it is sensor data that needs to be developed into a viewable image. Common reasons to convert:

• Nothing opens it. Most modern photo apps dropped CIFF support years ago. Lightroom, Photoshop, and many viewers that happily read a CR2 will refuse a CRW. Converting to JPG or PNG turns the orphaned raw into a file every device on earth can display.
• You're rescuing an old archive. Photos from a 2002 EOS D60 or PowerShot G3 are often the only CRWs people still have. Converting to a 16-bit TIFF preserves the full tonal range as a future-proof master; converting to JPG makes a quick shareable copy.
• You need to edit. Bringing the developed image into a modern editor is far easier as a 16-bit PNG or TIFF than fighting a viewer that can't decode CIFF.
• You want web-ready output. For a gallery or blog, a WebP or JPG is smaller and loads faster than asking a browser to handle raw it cannot read anyway.

CRW vs. Its Common Targets

Frequently Asked Questions

What program opens a CRW file?

Very few modern ones. CRW uses Canon's old CIFF container rather than the TIFF-based structure of CR2, so most apps that read a CR2 still cannot decode a CRW. Canon's own legacy Digital Photo Professional, older Lightroom builds, and a few raw utilities like RawTherapee or darktable can still handle it, but mainstream viewers and recent Photoshop/Lightroom releases generally cannot. Converting to JPG or PNG is the reliable way to make the image openable everywhere without hunting for legacy software.

Is CRW the same as CR2?

No — they are two generations of Canon raw. CRW (Canon Raw version 1) uses the CIFF container and came from early bodies like the EOS D30/D60/10D and PowerShot G-series, roughly 2000–2004. Canon replaced it in 2004 with CR2 (Canon Raw version 2), which is built on the TIFF structure and shipped first on the EOS-1D Mark II; CR3 followed in 2018. They share Canon raw DNA but are not interchangeable, and a tool that reads CR2 will often reject CRW.

Will I lose quality converting CRW to JPG?

Some, but it is controllable. CRW holds 12-bit raw sensor data; JPG is 8-bit and lossy, so the conversion bakes in white balance and tone curve and discards the extra editing headroom raw gives you. With the Quality Preset on "Very High" the visible loss is minimal and the image looks identical at normal viewing sizes. If you want to keep the full editing latitude, convert to a 16-bit TIFF or PNG instead — those preserve far more of the original tonal range than a JPG can.

What's the best format to convert CRW to for archiving?

A 16-bit TIFF. TIFF stores the developed image losslessly and supports a 16-bit depth that preserves the wide dynamic range of the raw capture, which is why print labs and archives accept it as a master. Set the Image File Extension to TIFF and Bit Depth to "16-bit (High Precision)" before converting. Keep your original CRW too if you can — it remains the only file with the untouched sensor data — but a TIFF is the practical, openable archival copy.

Does converting CRW keep the EXIF metadata?

The standard shooting metadata that matters to most people — capture date, camera model, exposure, ISO, and focal length — is carried into the output where the target format supports it, so a converted JPG or TIFF generally retains its EXIF block. Some Canon-proprietary maker-note fields specific to CIFF may not survive the format change, since they have no equivalent in the destination. In our testing, a CRW from an EOS D60 converted to JPG kept its date, camera, and exposure fields intact in the resulting EXIF.

Can I convert several CRW files at once?

Yes. Drop a whole batch of CRWs onto the uploader and each one is processed independently in parallel, then handed back individually or as a single ZIP — useful for developing an entire old shoot in one pass. If you would rather not commit to a single output type, the broader image converter accepts CRW alongside other raw formats and lets you pick the target per job.

Is it safe to upload my CRW files here?

Yes. Files travel over an encrypted (TLS) connection, are processed on our servers, and are deleted automatically after a few hours — there is no sign-up, no watermark, and nothing is shared or made public. For one-off old family photos that often means the safest path is simply to convert, download the JPG or TIFF, and let the originals expire from the server on their own.
