Merge ARW to PDF

How to Merge ARW to PDF Online

1. Upload Your ARW Files: Drag and drop your Sony Alpha .arw files, or click "+ Add Files" to select them. Reorder pages by dragging tiles into the sequence you want — page 1 is the first tile, and so on.
2. Pick Combine, Page Layout, and Paper Size: Default is Single PDF (all images in one document). Switch to Individual PDFs to get one PDF per ARW. Set Page layout to Portrait or Landscape, and pick a Paper size preset (A4 default, plus Letter, Legal, Tabloid, Ledger, Executive, A3, ARCH A/B, ISO B4/B5, or "Original" to match each photo's native dimensions).
3. Set Image Placement, Alignment, and Margin (Optional): Image placement is Cover (fills the page, may crop) or Contained (fits within margins, no crop). Image alignment controls vertical position when Contained — Top, Center, or Bottom. Margin options are No margin (0"), Narrow (0.5"), Moderate (0.75x1"), Normal (1"), or Large (2x1").
4. Tune Quality and Merge: Adjust the Image Quality (%) slider (default 75) and choose Image Transparency (Unchanged or Removed). Click Merge — files process in your browser session, no sign-up, no watermark.

Why Merge ARW to PDF?

ARW (Sony Alpha Raw) has been Sony's RAW container since the 2006 Alpha DSLR-A100, and is still used across the modern A7, A7R, A7S, A9, A1, FX, and ZV-E lineup. ARWs hold up to 14-bit sensor data with full white-balance, exposure, and color metadata — but no consumer device or browser displays them natively. You need Sony's Imaging Edge, Adobe Camera Raw, Lightroom, Capture One, or a third-party viewer to even see the photo. Bundling a shoot into a PDF turns that "you need pro software to look at this" file into something a client or printer can open from any phone, laptop, or email attachment.

• Client proofs and selects — Photographers shooting weddings, real estate, or portraits often deliver a PDF contact sheet so clients can star/circle the keepers before the editor opens Lightroom for the final pass. A PDF is universally readable and email-friendly in a way an .arw zip is not.
• Portfolio and submission decks — Galleries, contests, and editorial pitches typically ask for a PDF portfolio (sometimes with a strict page count or paper size). Merging A7 IV or A1 ARWs to A4/Letter PDF puts the work in the format the recipient actually wants.
• Archival and ESI — A PDF is a single, indexed, OS-independent container. Studios print proof PDFs alongside the working ARWs as a quick visual index when archiving shoots to cold storage.
• Legal, insurance, and inspection — Adjusters, surveyors, and inspectors who shoot Sony bodies in the field need their RAWs in a format the claims system or court will accept. PDF is the lowest-common-denominator ESI format.
• Print-shop handoff — Local print shops rarely accept ARW. A Prepress-quality PDF with Cover placement and zero margin gives the operator something they can RIP without conversion guesswork.
• Offline review — A merged PDF on a tablet means a photographer or art director can flip through a shoot on a flight without Lightroom installed.

ARW vs DNG vs JPEG — Format Comparison

Sony A7 IV RAW File-Type Sizes (Sony Official Spec)

Per Sony's ILCE-7M4 help guide, the A7 IV records ARW in three modes — useful context if you're choosing how aggressively the merger needs to compress the embedded preview:

Larger source ARWs mean larger embedded JPEGs in the output PDF — drop the Image Quality (%) slider to 60-70 and pick the Screen compression preset for a portfolio-friendly file under 10 MB; raise the slider to 90+ and pick Prepress or Printer for print-shop output.

Frequently Asked Questions

Will every Sony Alpha ARW work, including A1, A7 IV, and ZV-E1?

The merger reads ARWs from Sony's full Alpha lineage — DSLR-A100 (2006) through the current A7R V, A7 IV, A1, A9 III, FX3, and ZV-E1. As long as the file extension is .arw and it's a standard Sony RAW container (Uncompressed, Lossless Compressed L/M/S, or Compressed), it'll render to a PDF page. The full-resolution embedded preview is decoded; you don't need Imaging Edge installed.

Why is my ARW PDF much larger than the same shoot exported as JPEGs?

PDF embeds each image as a JPEG-compressed stream inside the document, but the page layout, fonts, and any margins add overhead. A 30-image PDF at A4/Quality 75 is typically 8-15 MB — roughly the same as 30 standalone JPEGs. If your PDF is significantly larger, drop Image Quality (%) to 60, switch Image placement to Contained (no upscaling), and recheck. For a smaller deliverable, run the result through a PDF compressor.

Does the merge preserve my ARW edits or just the camera-baked preview?

It uses the camera-baked full-resolution preview embedded in each ARW — that is, the JPEG Sony's processor wrote at capture time using your in-camera Picture Profile, Creative Look, and white balance. Lightroom or Capture One adjustments stored in sidecar XMP files are NOT applied. If you've done significant edits, export from Lightroom to JPEG or TIFF first, then merge images to PDF.

What's the difference between Cover and Contained placement?

Cover scales each photo to fill the page edge-to-edge, cropping whichever dimension overhangs — best for a clean, full-bleed portfolio look. Contained fits the entire image inside the printable area (respecting your Margin setting), so nothing is cropped but you'll see whitespace bars on the long axis if your photo's aspect ratio differs from the paper's. Sony Alpha shoots 3:2 by default, which fits A4/Letter (close to 1.41:1 / 1.29:1) with modest top/bottom margins in Portrait, or modest left/right margins in Landscape.

Can I get one PDF per ARW instead of a single combined document?

Yes. Switch Combine? from Single PDF to Individual PDFs. The output is a ZIP containing one PDF per uploaded ARW — convenient when you need to send each frame as a separate proof or attach a single shot to an email.

Which paper size should I pick for a portrait shoot vs. a wide landscape?

For portrait orientation shots (3:2 vertical from a Sony Alpha) on Portrait layout, A4 or Letter with Narrow margin gives you the largest visible image with breathing room. For landscape (3:2 horizontal), use Landscape layout at the same paper size, or pick Tabloid / A3 if you're delivering for large-format display. Choose Original under Paper size to make every PDF page exactly the source ARW's dimensions — useful for technical documentation where aspect ratio must be preserved exactly.

Will the EXIF data (ISO, shutter, lens) survive in the PDF?

The PDF stores the rendered image, not the camera EXIF. Capture date, ISO, aperture, shutter, focal length, and lens model are dropped because the merger only reads the embedded preview pixel data. If EXIF is critical for your workflow, convert ARW to JPG instead — that path keeps the full EXIF block in each output file.

Can I add captions, watermarks, or page numbers?

The merger doesn't add captions, watermarks, or page numbers in this release — it produces a clean image-per-page PDF. For watermarked client proofs, export from Lightroom with a watermark preset first, then merge the JPEGs. For page numbers or captions, open the merged PDF in Acrobat, Preview, or PDF-XChange and add a header/footer there.

What about other camera RAWs — Canon, Nikon, Fuji?

Use Merge CR2 to PDF for Canon, Merge NEF to PDF for Nikon, or Merge DNG to PDF for the Adobe Digital Negative format that Fuji, Pentax, and several phone cameras use. Each is tuned for the source format's embedded preview structure.
