What raw photos are and why you might convert them

A raw photo is the unprocessed data your camera captures — it contains more color information and detail than a JPEG, but it takes up much more storage space and most devices cannot open it. When you convert a raw file to JPEG, you are compressing it into a format that works everywhere: email, social media, printing, sharing with clients or collaborators.

The trade-off is permanent. A JPEG throws away some of the original detail to make the file smaller. Once you convert, you cannot get that detail back. So the typical workflow is to keep your raw files as backups, make your edits in a raw editor, then export a JPEG version for sharing or printing.

You do not need to convert every raw file. If a photo is a throwaway or a test shot, converting it saves you nothing. But if it is a keeper — something you edited, something you might print, something you want to send to a client — converting to JPEG makes it usable on any device and any platform.

Key Takeaways

  • Raw files contain more detail than JPEGs but take up 3 to 5 times more storage and cannot be opened on most devices or phones.
  • Converting to JPEG is a one-way process; you lose detail that cannot be recovered, so edit your raw file first, then export the JPEG.
  • Most raw editors (Lightroom, Capture One, Darktable) let you export JPEG directly without needing a separate conversion tool.
  • JPEG quality settings range from 80 to 95 for most uses; anything lower looks visibly worse, anything higher wastes file size.
  • Keep your original raw files in case you need to re-edit or re-export with different settings later.

Using Lightroom to convert raw to JPEG

Adobe Lightroom is the most common tool for this because most photographers already use it for editing. Open your raw file, make any edits you want (exposure, color, cropping), then go to File > Export Photos. Choose JPEG as the format. Set the quality slider to 85 or 90 — this is high enough that the loss is invisible to the human eye, but low enough that the file stays reasonably small.

In the same export window, you can choose where to save the JPEG, what to name it, and whether to resize it. Many photographers add a suffix like "_final" or "_web" to the filename so they can tell the JPEG apart from the raw file at a glance. If you are exporting for the web, you can also resize the image to a specific width (like 2000 pixels) to save even more space.

Lightroom remembers your export settings, so if you convert many photos the same way, you only have to set it up once. Click "Add" to save your settings as a preset, then future exports take one click.

Converting raw files in Capture One or other professional editors

Capture One Pro and Darktable (free, open-source) both work the same way: edit your raw file, then export or save as JPEG. Capture One calls it "Process" instead of "Export," but the idea is identical. You choose JPEG, set the quality, and pick a destination folder.

Capture One tends to give you more granular control over JPEG compression and color space, which matters if you are preparing images for professional printing. Darktable is free and works on Windows, Mac, and Linux, but the interface is less intuitive if you are new to raw editing. Both preserve your original raw file and create a separate JPEG.

Converting raw files without editing software

If you do not own Lightroom or another raw editor, you have a few options. Many cameras come with free software that can open raw files and export them as JPEG — check your camera manufacturer's website. Canon has Digital Photo Professional, Nikon has ViewNX-i, Sony has Imaging Edge. These tools are basic but they work.

Online converters like CloudConvert or Zamzar let you upload a raw file and read a JPEG, but they send your photo to someone else's server. If privacy matters to you, this is a risk. For one or two photos it may be fine; for a whole shoot, it is not practical.

The free option that works on any computer is Darktable, which you can read from darktable.org. It handles raw files from most camera brands and exports to JPEG. The learning curve is steeper than Lightroom, but the cost is zero.

Understanding JPEG quality settings and file size

JPEG quality is usually shown as a number from 1 to 100, or sometimes as a slider. The relationship between quality and file size is not linear. A quality-95 JPEG might be only 10 to 15 percent larger than a quality-85 JPEG, but the visible difference is tiny. A quality-70 JPEG is noticeably softer and blockier, especially in shadows and fine details.

For most uses — sharing online, printing up to 8x10 inches, sending to clients — quality 85 to 90 is the sweet spot. For web-only images that will never be printed, quality 80 is acceptable. For images you might print large or use professionally, stick with 90 or higher.

File size also depends on the image itself. A photo with lots of solid colors (a blue sky, a white wall) compresses much smaller than a photo with fine texture (grass, fabric, hair). A 24-megapixel photo at quality 85 might be 3 to 5 MB; the same photo at quality 95 might be 6 to 8 MB.

Organizing your raw files and JPEG exports

A common workflow is to keep raw files in one folder and export JPEGs to a separate folder. This makes it straightforward to find the version you need: raw files for editing and backup, JPEGs for sharing and printing. You can name them the same (photo_001.raw and photo_001.jpg) so they stay paired.

Some photographers create subfolders by date or project: 2024-01-15_wedding_raw and 2024-01-15_wedding_jpeg. Others use a naming convention like "photo_001_raw" and "photo_001_final" to keep them in the same folder but clearly separate. Pick a system that makes sense to you and stick with it, because you will have hundreds or thousands of files eventually.

Back up your raw files to an external drive or cloud storage. JPEGs are straightforward to recreate from the raw file, so they do not need the same level of backup. But if your raw files are lost, you cannot get that original detail back.

When not to convert to JPEG

If you are still editing a photo or might edit it differently later, keep it as raw. JPEG is final — once you export it, you cannot undo the compression or recover lost detail. If you are not sure whether you will use a photo, do not convert it yet. Storage is cheap; re-editing a JPEG that should have stayed raw is frustrating.

If you are archiving photos for the long term, raw is better than JPEG because it preserves more information. JPEG is a lossy format, meaning it discards data to save space. Raw formats vary by camera brand, but they preserve everything the sensor captured. For archival purposes, some photographers convert raw to DNG (Digital Negative), an open-source raw format that is more likely to be readable in 20 years.

Frequently Asked Questions

Can I convert a JPEG back to raw?

No. Once a photo is compressed to JPEG, the lost detail is gone forever. You cannot recover it by converting back. This is why photographers always keep the raw file if they might want to edit the photo again later.

What if my camera brand is not supported by my editing software?

Most major raw editors (Lightroom, Capture One, Darktable) support raw files from Canon, Nikon, Sony, Fujifilm, Pentax, and others. If your camera is very new, the software might not recognize it yet — check the manufacturer's website for an update. If your camera is very old or obscure, Darktable or your camera's own software are your best bets.

Does converting to JPEG reduce image quality noticeably?

At quality 85 or higher, the loss is invisible to most people on screen or in prints up to 11x14 inches. Below quality 80, you may see softness or blockiness in shadows. The best approach is to export one test image at different quality levels and compare them on your monitor and in a print.

Can I batch convert multiple raw files at once?

Yes. Lightroom, Capture One, and Darktable all let you select multiple photos and export them together with the same settings. This is much faster than converting one at a time. In Lightroom, select all the photos you want, then go to File > Export Photos and choose your settings once.

What color space should I use when exporting to JPEG?

Use sRGB for anything going on the web or to people who might view it on different devices. Use Adobe RGB only if you are printing professionally and your printer supports it. Most online platforms and phones expect sRGB, so that is the safe default.
