File converter for Mac: six options by task

Updated: 2026-10-29

Short answer

Choose a file converter for Mac by the job you need to do. Try Preview for an occasional image export, ImageOptim for image optimization, Clop for clipboard or watch-folder automation, Permute for media conversion, Tangerine for its drag-based catalog, or Yuzu Drag for supported file actions from Finder.

These are recommendations by task, not a universal ranking. We have not benchmarked their speed, compression ratios or output quality against one another.

Options at a glance: checked 2026-10-23

Option	Best for	Main trade-off
Preview	Occasional image export and PDF size reduction	Manual steps; available export types depend on the file
ImageOptim	Focused image optimization and metadata removal	Image-focused, not an all-file converter
Clop	Clipboard and watch-folder optimization	Check input support and automation settings for your workflow
Permute	Deeper media conversion workflows	Permute 4 requires macOS 26 and Apple silicon; older Macs need the offered Permute 3 route
Tangerine	Broader drag-based format coverage and App Store distribution	Apple silicon and macOS 13+
Yuzu Drag	Explicit conversion, compression and temporary staging	Check its supported operations; macOS 14+ required

The official links below support competitor claims. Choose the workflow and supported operations you need; Preview may already solve your occasional task.

Try the built-in macOS option first

For a photo conversion, open the image in Preview and choose File > Export. Select a format offered for that file, choose a new filename and save. For example, export a HEIC photo as JPEG when the destination does not accept the original. Open the exported copy to check appearance and compatibility. Apple's image conversion guide explains the method.

For a PDF attachment, choose File > Export and use the Reduce File Size Quartz filter. Save a separate copy and inspect it, especially small text and scanned pages. Reducing file size may affect readability. Apple's PDF size guide documents this route.

If the result meets the destination's requirements, stop there. Add an app when the task repeats often, you need a supported operation Preview does not offer, or you prefer another interaction.

Where each alternative is better

Preview: best for an occasional supported export

Preview is already on the Mac. It avoids another download for a single conversion and lets you inspect the file in the same app. Its limitation is not that it cannot convert images; it is that a repeated sequence of opening, exporting and checking may be less convenient for your day-to-day work.

ImageOptim: best for a focused image optimization workflow

ImageOptim markets drag-and-drop image optimization, EXIF/GPS removal, Finder Services and command-line use. The Mac desktop app is open source. The developer explicitly says there is no App Store version; its separate web/API offering should not be confused with the desktop app.

Choose it when image optimization is the whole job. Do not assume a specialist image optimizer is intended to replace a general media converter or a file shelf.

Clop: best for clipboard and watch-folder automation

Clop markets local image, video and PDF optimization with clipboard and watch-folder automation. It also describes target-size workflows, presets and pipelines. These are good reasons to choose Clop if you want optimization folded into copying or saving content rather than triggered manually each time.

Check Clop’s supported inputs and automation settings against your batch size and destination. A clipboard workflow and a manually triggered file conversion solve different problems.

Permute: best for deeper media conversion

Permute has broader media depth, including audio and advanced video workflows, plus presets, automation and drop zones. Choose it when those requirements matter more than a compact Finder action.

Version choice matters. Permute 4 requires macOS 26 and Apple silicon. The vendor offers Permute 3 for macOS 11–15, including Intel.

Tangerine: best for broader drag-based coverage and the App Store

Tangerine uses a drag-and-key interaction and markets offline conversion. Its tool catalog covers a broader range of formats and editing work than Yuzu's approved scope. Its App Store listing provides the store distribution route.

Choose it if that catalog or store purchase channel is important. It requires an Apple-silicon Mac and macOS 13 or later. Local processing is shared with other native utilities here, not a reason to declare one product uniquely private.

When Yuzu Drag fits

Yuzu supports Intel and Apple silicon on macOS 14 or later. It fits a deliberate workflow where you select a file, then decide what to do:

Begin dragging an HEIC photo in Finder.
Tap ⇧ for Convert.
Drop on JPG and inspect the new file.

For supported image, video or PDF compression, drag the file, tap ⌘ for Tools and drop on Compress. For temporary staging, drag a file, tap ⌘ for Tools, tap ⌘ again for Actions and drop on Float. These gestures do not imply every input can become every output. Check the tools hub and the relevant category before downloading for a specific conversion.

Conversion and compression create new files. Move and Rename change originals when you select those actions. Local processing is separate from deliberately chosen network-sharing actions.

FAQ

Do I need to install a converter for one photo?

Usually not if Preview can open and export it in the format you need. Try File > Export and inspect the new file first.

Which option is best for automatic clipboard optimization?

Clop explicitly focuses on clipboard and watch-folder automation. Yuzu's workflow described here is a deliberate file drag and action.

Are these apps ranked by output quality?

No. These are task-based recommendations, not a measured speed, quality or compression ranking. Test your own source files before choosing.
