Merge CRW to PDF

How to Merge CRW Files into a PDF Online

1. Upload Your CRW Files: Click "+ Add Files" or drag and drop your Canon CRW shots from a D30, D60, 10D, 300D, Pro1, G-series, or S-series. Batch upload is supported and the order you drop them in becomes the page order.
2. Pick Combine, Page Layout, and Paper Size: Under "Combine?" choose "Single PDF" (default) for one merged document or "Individual PDFs" to wrap each CRW in its own file. Set "Page layout" to Portrait or Landscape and "Paper size" to A4 (default), Letter, Legal, A3, Tabloid, or Original (matches the source CRW resolution).
3. Set Image Placement, Alignment, and Margin (Optional): Pick "Contained" (fit to margins, default) or "Cover" (fill the page, may crop). Align Top, Center, or Bottom. Choose Margin: No margin, Narrow (0.5"), Moderate, Normal (1"), or Large.
4. Tune Image Compression and Merge: Drag "Image Quality (%)" between 1 and 100 (default 75) and click "Merge." The PDF downloads to your browser. No watermark, no Canon Digital Photo Professional install required.

Why Merge CRW to PDF?

CRW is Canon's first digital RAW format, built on the CIFF (Camera Image File Format) specification released February 12, 1997. It shipped on Canon EOS DSLRs and PowerShots from 2000 through 2004 before being replaced by the TIFF-based CR2 (introduced with the EOS-1D Mark II / EOS 20D in 2004) and later the ISO BMFF-based CR3 (introduced with the EOS M50 in 2018). PDF turns those legacy raw archives into a single document any device can render — no dcraw, no Adobe Camera Raw legacy plug-in, no DPP3 install.

• Estate and inheritance archives — A box of CDs from a parent's late-2000s photo hobby often holds CRW files from a D30 or 300D Digital Rebel. Merging them into a dated PDF lets every relative open the photos on a phone without hunting for a 20-year-old RAW decoder.
• Insurance and damage claims — Adjusters frequently ask for one PDF rather than a folder of raws. Merging your CRW property documentation into Letter or A4 keeps EXIF-style ordering and gives the adjuster a single attachment under typical email caps.
• Submission portfolios for archival or grant programs — Museums, libraries, and historical societies receiving early-2000s digital photography prefer PDF deliverables. CRW files merged at high quality (95+) preserve detail without forcing reviewers to install Canon software.
• Court and legal exhibits — Court e-filing systems usually accept PDF only. A merged CRW-to-PDF lets you submit the original-shot ordering as exhibits while keeping a separate copy of the raws as evidence of provenance.
• Quick proofing for clients on legacy photo collections — When restoring or rescanning early DSLR work (D60, 10D weddings; PowerShot G2/G3 product shoots), a single PDF proof beats sending a 200 MB folder of CRW the client cannot open.
• Backup and migration off CIFF — Adobe deprecated direct CRW support in newer Camera Raw releases, and Canon's current Digital Photo Professional 4 dropped CRW entirely. A PDF merge is a no-loss display archive while you decide whether to also convert each CRW to DNG or TIFF for editing.

Frequently Asked Questions

What is a CRW file and why are mine hard to open today?

CRW is Canon's pre-2004 RAW format, based on the Camera Image File Format (CIFF) specification published in 1997. It was used on the EOS D30, D60, 10D, 300D Digital Rebel, PowerShot Pro1, G1–G6, and S30–S70. After Canon switched to CR2 in 2004, support for CRW gradually disappeared from mainstream tools — current Canon Digital Photo Professional 4 does not open CRW, and Adobe Camera Raw treats it as legacy. Open-source decoders like dcraw, darktable, and RawTherapee still read CRW, which is what most online converters use under the hood.

Will all my CRW files merge into one PDF in the order I uploaded them?

Yes. Drag-and-drop order in the upload list becomes the page order. To re-sort, drag thumbnails before clicking Merge. If you'd rather keep each shot separate, set "Combine?" to "Individual PDFs" and you'll get one PDF per CRW.

What page size should I pick for landscape Canon EOS D30 / D60 shots?

CRW from the D30 (3 MP, 2160×1440) and D60 (6 MP, 3072×2048) are 3:2 aspect ratio. For screen-only viewing pick "Original" — the PDF page matches the photo dimensions exactly with zero white space. For print, A4 or Letter in Landscape with Contained placement and Narrow margin is the closest fit; Cover placement crops a thin strip top and bottom because A4/Letter are not 3:2.

Are EXIF shooting details preserved in the PDF?

The CRW EXIF (shutter speed, aperture, ISO, white balance, lens info, camera body) is read to render the image but is not embedded as searchable PDF metadata in the merged output. If you need to retain those fields, convert each CRW to DNG or TIFF first with Convert CRW to TIFF — TIFF/DNG carry full EXIF — then merge the TIFFs. The PDF will still show the rendered image; the metadata stays in the source files.

Why are my CRW files different sizes than my friend's CR2 files?

CRW from a 3 MP EOS D30 is roughly 2–3 MB; a 6 MP D60 CRW is 5–7 MB. Modern CR2 from a 30 MP EOS 5D Mark IV runs 30–40 MB, and CR3 from a 45 MP EOS R5 runs 45–60 MB. Sensor resolution dominates file size; the format change (CIFF → TIFF → ISO BMFF) is secondary. If you're merging both eras together, lower-resolution CRW pages will look softer than higher-resolution CR2/CR3 pages on the same paper size.

Can I edit white balance or exposure during the merge like Lightroom would?

No. This tool renders the CRW with the camera's recorded settings (white balance, picture style, exposure compensation) and then places the rendered JPEG into the PDF. For non-destructive RAW editing you still need a RAW developer — darktable and RawTherapee are free and read CRW; Adobe Lightroom Classic still imports CRW through legacy Camera Raw. After developing, export to JPG or TIFF and merge those instead.

What's the difference between Cover and Contained placement?

Contained fits the entire CRW frame inside the page minus the margin — you see the full photo, often with white bars on two sides if the photo aspect (3:2) doesn't match the paper aspect (Letter is 1.29:1, A4 is 1.41:1). Cover scales the photo to fill the entire page edge to edge — no white space, but the long sides of a 3:2 frame get cropped. Photo-book style printing usually wants Cover with Center alignment; archival proofs usually want Contained.

Should I also convert my CRW files to DNG for long-term storage?

Recommended, yes. Adobe's free DNG Converter still reads CRW and exports DNG, which is an open ISO/TIFF-based RAW format that more tools will support 20 years from now than CIFF-based CRW. The PDF merge here is for sharing and viewing; DNG (or Convert CRW to JPG for casual sharing) is the better preservation path for the underlying raw data.

Can I merge CRW files together with CR2, CR3, JPG, or HEIC?

This page accepts CRW only. If you have a mixed set, convert the CRW shots to JPG first, then use Merge JPG to PDF, or run separate merges per format and combine the resulting PDFs in any free PDF combiner. For modern Canon raws specifically, see Merge CR2 to PDF and Merge CR3 to PDF.
