Convert TIFF to JPG on Mac Free — No Photoshop Needed

Mac has three good free options for converting TIFF to JPG: a browser-based tool (no software, any Mac), Preview (built into macOS, handles single and batch files), and Automator (for recurring workflows). Here's when to use each and exactly how each one works.

Method 1: Browser tool — fastest, no software needed

The browser tool at the top of this page works on any Mac running Chrome, Safari, or Firefox. No installation, no Photoshop subscription, no Lightroom catalog required.

1. Open this page in Chrome or Safari on your Mac.
2. Drag your .tiff files from Finder directly into the browser drop zone. You can drag a whole folder's contents at once (select all files in Finder with Cmd+A, then drag).
3. Set quality (90 is good for photos; 82 for scanned documents).
4. Click Convert. Processing happens in your browser using your Mac's graphics and memory.
5. Click "Download All" to get a zip of all JPGs, or download each file individually.

For a 20-file batch of 50MB TIFFs, expect 1–3 minutes on a MacBook Air M1 or newer. Intel Macs are slower but handle it fine.

This is the fastest option for one-time conversions. Nothing to configure, no software to install, nothing uploaded to Apple or any other server.

Method 2: Preview — built into every Mac

macOS Preview can export any image it can open, including TIFF, to JPG. For single files:

1. Open the TIFF file in Preview (double-click it in Finder — Preview is the default for most image types).
2. Go to File > Export.
3. In the export dialog, click the Format dropdown and select JPEG.
4. Adjust the Quality slider.
5. Choose your save location and click Save.

Batch conversion with Preview: Preview can also batch-export multiple TIFFs, but the interface is less obvious:

1. Select all your TIFF files in Finder.
2. Open them all at once in Preview (right-click > Open With > Preview).
3. In Preview's sidebar, select all thumbnails (Cmd+A).
4. Go to File > Export Selected Images.
5. Choose a destination folder and set Format to JPEG.
6. Click Choose. Preview exports all selected images.

Preview's limitation: you can't set quality per-file and the quality slider isn't as precise as a dedicated converter. But for quick single-file exports, it's perfectly capable.

Method 3: Automator — for recurring batch workflows

If you regularly receive TIFF files that need to be converted to JPG, Automator can create a "folder action" that converts files automatically when they land in a designated folder.

1. Open Automator (in Applications or via Spotlight).
2. Choose "Folder Action" as the workflow type.
3. Set the target folder (e.g., a "TIFF Inbox" folder on your Desktop).
4. Search for "Scale Images" — add it and set it to the dimensions you want (or skip this step if you don't need resizing).
5. Search for "Change Type of Images" — add it and choose JPEG as the output type.
6. Optionally add "Move Finder Items" to send the converted JPGs to an output folder.
7. Save the workflow. From now on, any TIFF you drop into the target folder auto-converts to JPG.

Automator is free, already on your Mac, and requires no coding. The downside: quality control is limited compared to manual conversion — Automator's JPEG quality defaults are decent but not adjustable without additional steps.

Which method should you use?

Here's the quick decision tree:

• One-time batch of any size, quality matters: Use the browser tool. Full quality control, handles large batches, works on any Mac.
• Single file, quick and simple: Use Preview. It's already open on your Mac and the export takes 20 seconds.
• Ongoing workflow, files arrive regularly: Set up Automator. One-time setup pays off over hundreds of future conversions.
• You need precise color management for print: Neither browser tools nor Preview match the color management capabilities of Photoshop or Affinity Photo. If that's required, Affinity Photo (one-time purchase, no subscription) is the best alternative to Photoshop.

For most Mac users converting TIFF files for web or email use, the browser tool is the fastest path. Preview works great for single files. Automator solves the "I do this every day" problem.

For Windows users, the TIFF to JPG on Windows guide covers the equivalent options.

Frequently Asked Questions

Can Preview batch convert TIFF to JPG on Mac?

Yes — open multiple TIFFs in Preview at once, select all in the sidebar with Cmd+A, then go to File > Export Selected Images. Set Format to JPEG, choose a destination folder, and Preview exports all of them. It's less flexible than dedicated tools (no per-file quality settings) but works fine for simple batches.

Does the browser tool work on older Intel Macs?

Yes, though large TIFFs (80MB+) will take longer than on Apple Silicon. An Intel MacBook Pro from 2018–2020 handles 50MB TIFFs comfortably, typically in 5–10 seconds per file. Very large files (150MB+) may take 30–60 seconds per file on older hardware.

Will macOS change my TIFF files if I open them in Preview?

No. Opening a TIFF in Preview for viewing does not modify the file. Only File > Export (not File > Save As, which would overwrite the original) creates a new output file. The original TIFF remains unchanged.
