ARW to PDF Converter

Convert ARW to PDF: What This Tutorial Covers

This walks you through turning a Sony ARW raw photo into a shareable PDF — and explains what you trade away in the process. An ARW holds the unprocessed sensor readout from a Sony Alpha camera; to put it on a PDF page it has to be demosaiced and rendered to a normal image first, so the conversion fixes one rendering and drops the editing latitude that makes raw useful. This is the right move for sending a proof, printing a contact sheet, or archiving a flat copy, but the wrong move if you still need to recover highlights or re-balance white in an editor.

How to Convert ARW to PDF

1. Upload Your ARW File: Drag and drop your .arw files onto the page, or click "+ Add Files" to browse. Multiple ARW files can be queued and converted in one batch.
2. Pick Single PDF or Individual PDFs: Choose "Single PDF" to combine every uploaded photo into one multi-page document, or "Individual PDFs" to get one PDF per ARW file.
3. Set Paper Size, Orientation, and Placement: Open Advanced Options to set "Paper size" (A4 by default), "Portrait" or "Landscape", and whether the image is "Contained" (whole frame fits, with margin) or "Cover" (fills the page, edges cropped).
4. Convert and Download: Click "Convert" and download the PDF. No sign-up, no watermark.

Walk-through: Getting the Page to Match the Photo

The two settings that most often produce a surprising result are placement and orientation, because a PDF page has a fixed aspect ratio and your photo almost certainly does not.

• You want the entire photo visible: keep "Contained" with "Center" alignment. The longest edge of the image fits the page and you get even borders — best for proofs and prints where nothing should be cropped.
• You want a full-bleed, edge-to-edge page: switch to "Cover". The image scales until it fills the page and the overhanging edges are trimmed, so a 3:2 photo on an A4 page loses a strip top and bottom (portrait) or left and right (landscape).
• The photo looks rotated 90 degrees: Sony tags orientation in EXIF, but if a frame was shot in an unusual hold the auto-rotation can miss. Set "Landscape" or "Portrait" to match the photo's longer dimension.
• You want it tight to the camera's own dimensions: choose "Original" in the "Paper size" dropdown so the page matches the rendered image rather than a fixed paper standard, then set the "Narrow (0.5")" or "No margin (0")" spacing.
• The PDF is larger than you need to email: lower the "Quality Percentage" slider (it controls the JPEG quality of the embedded image) — 75 is a good balance, and dropping toward 50 noticeably shrinks the file with little visible loss at screen size.

Common Errors and How to Fix Them

• "Colors look flat or washed out." Raw files store a wide tonal range with no contrast curve baked in. The converter applies a standard render, so a deliberately flat-exposed raw can look dull. If you want the punchy look, apply your edits in a raw processor first, export a JPEG, then make the PDF from that.
• "The PDF is huge." A 14-bit ARW rendered at full resolution is a large image. Lower "Quality Percentage", choose the "Ebook" or "Screen (Best)" compression preset, or downsize the source before converting if you only need it for email.
• "Part of my photo is cut off." That is the "Cover" placement cropping to fill the page. Switch to "Contained" to keep the whole frame.
• "My edits in Lightroom didn't carry over." Raw edits live in a sidecar or catalog, not inside the ARW pixels. Export the edited frame to JPEG or TIFF from your editor first, because a direct ARW conversion only ever renders the camera's baseline interpretation.
• "The file won't upload." Confirm it is a real Sony .arw; renamed or partially copied raws can fail to parse. ARW frames from very new camera bodies sometimes lag third-party tool support.

When This Doesn't Work

A direct ARW-to-PDF conversion is a one-way flatten: it renders the camera's baseline interpretation of the sensor data and discards the recovery headroom that makes raw worth shooting. If you still need to pull back blown skies, fix white balance, or lift shadows, do that in a raw editor (Lightroom, Capture One, DxO PhotoLab, or the free RawTherapee, all of which read ARW) and export a finished JPEG or TIFF, then build the PDF from that. If you only want the photo as a standard image rather than a document, convert ARW to JPG instead. The same render-then-place workflow applies to other camera raws — Canon shooters can convert CR2 to PDF the same way.

Frequently Asked Questions

Will I lose image quality converting ARW to PDF?

You lose raw editing latitude, not necessarily visible detail. The ARW's 12- or 14-bit sensor data is demosaiced and rendered to a standard 8-bit image, then embedded in the PDF as a JPEG whose quality you set with the "Quality Percentage" slider. At a high quality setting the picture looks the same on screen and in print; what is gone is the ability to recover highlights, shadows, and white balance the way you could from the original raw.

Is the ARW file uploaded to your servers, and how long is it kept?

Yes — your ARW is sent over an encrypted connection and rendered on our servers, not in the browser, because raw demosaicing and PDF assembly run server-side. Both the uploaded ARW and the finished PDF are deleted automatically a few hours after conversion. There is no sign-up, no watermark, and files are never shared or made public.

Does the PDF keep my camera's EXIF and lens metadata?

No. ARW carries rich metadata — exposure, lens, AF points, and Sony's in-camera profiles — but converting to PDF produces a flat rendered image on a page, so that shooting metadata is not preserved in the document. If you need the EXIF, keep the original ARW alongside the PDF or export to a format like JPEG that can retain it.

Why does my ARW look different here than in Lightroom?

Lightroom applies Adobe's default raw profile (and any edits you made), while this converter applies its own standard render of the same sensor data. Two raw processors will almost always interpret the same ARW slightly differently in contrast and color, because raw has no single "correct" rendering baked in. For a match to your edited version, export the finished image from Lightroom first and convert that.

Can I put several ARW photos into one PDF?

Yes. Upload all of them and choose "Single PDF" to get one multi-page document with one photo per page; choose "Individual PDFs" to download a separate PDF for each. Page size, orientation, and placement apply to every page in the batch.

What is an ARW file, exactly?

ARW (Sony Alpha Raw) is Sony's proprietary raw photo format, built on the TIFF structure and introduced in 2006 with the Alpha DSLR-A100. It stores the camera sensor's unprocessed Bayer data at 12 or 14 bits per channel, and depending on the camera and setting it can be uncompressed, lossy-compressed, or — on recent bodies — losslessly compressed. In our testing, a 24-megapixel ARW renders to a sharp full-page A4 PDF at the default 75% quality with no visible artifacts at normal viewing distance.
