Merge CR3 to PDF

How to Merge CR3 Files into a PDF Online

1. Upload Your CR3 Files: Drag and drop or click "+ Add Files" to select Canon RAW photos from EOS R-series, EOS M50/M50 II, EOS 90D, EOS RP, or PowerShot G7 X Mark III. Batch is supported — drop in an entire shoot folder. Each CR3 becomes one page in the PDF, in upload order (drag rows to reorder before merging).
2. Pick Combine, Paper size, and Page layout: Default is Single PDF (combines all pages); switch to Individual PDFs to get one PDF per CR3 instead. Set Paper size to A4 (default), Letter, Legal, A3, Tabloid, Ledger, Executive, ISO B4/B5, or Arch A/B. Set Page layout to Portrait (default) or Landscape — landscape suits horizontal frames from a wide-angle 24-70mm.
3. Tune Image placement, alignment, and Margin (Optional): Choose Image placement Cover (fills the page edge-to-edge, may crop) or Contained (default — fits inside margins, preserves aspect). Set Image alignment to Top, Center (default), or Bottom. Pick a Margin preset: No margin (0"), Narrow (0.5", default), Moderate (0.75x1"), Normal (1"), or Large (2x1") — Normal matches print-house bleed expectations.
4. Set Image Quality, Transparency, and Merge: Drag Image Quality (%) between 1-100 (default 75 — the sweet spot for shareable proofs). Set Image Transparency to Unchanged or Removed (replaces alpha with white, useful if a downstream RAW converter wrote PNG-style alpha). Click Merge — files process in your browser session, no sign-up, no watermark.

Why Merge CR3 to PDF?

CR3 is Canon Raw v3, the proprietary RAW format Canon introduced in 2018 with the EOS M50 (the first Canon body to ship with the DIGIC 8 image processor). Unlike its TIFF-based predecessor CR2, CR3 is built on the ISO Base Media File Format (ISO/IEC 14496-12) and uses Canon's crx codec, which supports both lossless RAW and the smaller lossy C-RAW (roughly 30-40% smaller than lossless CR3 with no resolution loss). Merging CR3s into a single PDF is the fastest way to share Canon RAW photography without forcing every recipient to install RAW software.

• Wedding and event proofs — Send 50-200 frames as one ~30 MB PDF instead of 50-200 multi-megabyte CR3s your client cannot open. Pair Contained placement with Narrow margins and 75% Quality for clean proof sheets that fit inside Gmail's 25 MB attachment cap or attach cleanly to a client portal.
• Portfolio and review submissions — Photo contests, art-school reviews, and stock-agency submissions often require a single multi-page PDF. Cover placement on Letter or A3 fills the page and looks portfolio-grade for landscape series shot on an EOS R5 or R6 Mark II.
• Camera-club and Lightroom alternatives — If your camera club shares CR3s in WhatsApp or Discord, the average member without Adobe Camera Raw 11+ or macOS Catalina+ Preview cannot open the file. A merged PDF works on every phone and laptop made in the last decade.
• Archival and contact sheets — Bundle a date's full take into one searchable PDF for backup. PDF readers index page numbers, so you can reference "page 47 from Saturday" instead of digging through filenames like IMG_4721.CR3.
• Email-friendly delivery to non-photographers — Wedding planners, real-estate agents, and event coordinators rarely have RAW workflows. A 12 MB PDF with 24 pages of decoded JPEG renders previews instantly in Gmail, Outlook, and Apple Mail without any plugin.

Frequently Asked Questions

Why merge CR3 to PDF instead of CR3 to JPG?

A PDF gives the recipient one file with all photos in a fixed page order — no zip extraction, no sorting by filename. JPGs are fine for one or two photos but become unwieldy for a 50-frame shoot. If you only need single-image conversion, see CR3 to JPG or CR3 to PNG instead. For a single CR3 inside a PDF wrapper (no page combining), use CR3 to PDF.

Which Canon cameras shoot CR3?

Every Canon body running DIGIC 8 or newer: EOS M50 (2018, the first), EOS M50 Mark II, EOS M6 Mark II, EOS 90D, EOS RP, EOS R, EOS Ra, EOS R5, EOS R6 / R6 Mark II, EOS R7, EOS R8, EOS R10, EOS R50, EOS R3, EOS R5 Mark II, PowerShot G7 X Mark III, and PowerShot SX70 HS. Older Canon DSLRs (5D Mark IV, 7D Mark II, 80D, etc.) shoot CR2 — for those, use CR2 to PDF merge.

Will I lose RAW editing latitude when merging to PDF?

Yes — PDF embeds a rendered (decoded) image, not the RAW sensor data. White balance, exposure, and shadow recovery are baked in at the moment of conversion using a default Adobe-style demosaic. Always keep the original CR3s for editing; the PDF is for sharing only. If you need full RAW editing, send the .cr3 files and ask the recipient to use Canon Digital Photo Professional (free), Adobe Camera Raw 11.0+, Lightroom Classic, DxO PhotoLab, Capture One, or darktable 3.8+.

How do I get a portfolio-style page with no margin?

Set Margin to "No margin (0")", Image placement to Cover, and Page layout to match your image orientation (Portrait for vertical frames, Landscape for horizontal). Cover placement fills the page edge-to-edge but may crop the image to fit the paper aspect — for a 3:2 sensor on A4 (≈1.41:1), expect a slight top-and-bottom crop in landscape or left-and-right crop in portrait. Use Contained if you need every pixel preserved.

What's the difference between Single PDF and Individual PDFs?

Single PDF combines all uploaded CR3s into one multi-page PDF in upload order — the typical merge workflow. Individual PDFs generates one PDF per CR3 input file (no merging) and packages them as a ZIP for download. Use Individual PDFs when you need each frame as its own deliverable (e.g., per-image client approval workflows or per-photo metadata stamping in a downstream tool).

Why is my merged PDF so much larger than the originals?

CR3 stores raw sensor data with strong codec compression — a 24 MP lossless CR3 is typically 24-30 MB. When merged to PDF, each frame is decoded to a full-resolution image (often 6000x4000 pixels) and re-encoded as JPEG inside the PDF. Default 75% quality usually produces a smaller PDF page than the source CR3, but if you set Quality to 95-100% on a 30-frame batch, the PDF can balloon past the originals. Drop Quality to 70-80% and pick Compression Type: Screen in Image Compression for the smallest files.

Can I add a cover page or photographer credit?

Not directly in this tool — XConvert merges photos into pages, no text overlay. For a cover page, render one in Photoshop, Affinity Publisher, or Canva, export as a single-page PDF or JPG, and merge it ahead of the CR3s. After merging, you can prepend or stitch additional PDFs together with merge JPG to PDF (if your cover is a JPG export) or compress the final file with Compress PDF before sending.

Will EXIF metadata (camera, lens, ISO, shutter speed) carry over?

The merge process renders the image only — EXIF tags from the CR3 are not embedded in the PDF page. If your client needs shooting data, export CR3 to JPG separately (EXIF preserved by default in JPEG export) or include a separate metadata sheet. PDF supports XMP metadata at the document level but per-image EXIF requires a different workflow.

Does this work for mixed CR3 + JPG batches?

This page accepts CR3 only. For mixed batches (CR3 from your camera plus JPGs from a phone), convert the CR3s to JPG first via CR3 to JPG, then use merge JPG to PDF on the combined set. The two-step keeps page ordering precise.
