What is JPEGmini?
JPEGmini is a Mac app that re-encodes JPEG photographs to make them smaller without the picture visibly changing. It is built by Beamr and works inside the baseline JPEG standard, so the output opens in anything that reads a JPEG — the app is not a converter and does not change the format. Beamr's technology page claims reductions of up to 80%, or five times smaller, on digital photographs, and the same page describes the two-part method: an image-quality detector that decides how far each photo can be pushed, and an encoder that adapts to that photo rather than applying one quality setting everywhere. The desktop app is a one-time purchase with a free tier that allows 50 images a day; the paid tiers add unlimited files, video compression and plugins for Lightroom, Photoshop and Capture One.

Key features
What JPEGmini does at a glance.
Re-encodes JPEG photographs to reduce file size while staying inside the baseline JPEG standard
Quality detector decides the maximum compression
For each photo individually rather than applying one setting to a batch
Converts HEIC files to JPEG as part of the optimisation pass
Batch processes a folder of images
Without per-file intervention
Handles panoramas and large images
Up to 512 megapixels
Pro adds H.264 and H.265 video compression alongside the image work
Optional plugins optimise
In place from Adobe Lightroom, Adobe Photoshop and Capture One without an export step
Automations tier watches a folder and auto-optimises, resizes and exports new files in the background
What you can use JPEGmini for
- Shrinking a photo library before archiving it or uploading it
- Preparing web-sized images for a site without a manual export step
- Cutting a delivery gallery down to a size a client can download
- Optimising images straight out of Lightroom, Photoshop or Capture One
- Reducing storage and bandwidth for a large image collection
Who is JPEGmini for?
- Photographers who deliver large numbers of JPEGs and want smaller files without a visible change
- Anyone who wants a set-and-forget batch optimiser rather than a manual editor
- Studios that already work in Lightroom, Photoshop or Capture One and want the optimisation inside that workflow
Who is JPEGmini not for?
- Anyone who needs PNG, WebP or SVG optimisation — JPEGmini works on JPEG and HEIC, and other formats need a different tool
- Users who want open source or a one-off free tool, since the useful tiers are paid and the free tier is capped at 50 images a day
- People on macOS 13.4 or earlier, as version 4.5.1 sets its floor at macOS 13.5
Compatibility
Supported formats: JPEG, HEIC, H.264, H.265
Limitations
- The free tier is capped at 50 images per day on one device and only compresses video during the seven-day trial
- The paid licence includes one year of free updates; continued updates after that are not covered by the purchase
- Only JPEG and HEIC are handled. PNG, WebP, GIF and SVG are outside the app's scope
- Beamr's technology page claims reductions of up to 80% while the pricing page states up to 70%; both are first-party figures and the two do not agree
- The desktop app is separate from JPEGmini Cloud, the browser-based gallery product sold on its own subscription
Strengths and trade-offs
What JPEGmini does well, and what to weigh before choosing it. Points marked developer-stated come from the developer’s own material and have not been independently confirmed.
Strengths
- Works inside the standard JPEG format, so output files open in any browser, photo app or device without a conversion step.Developer-stated
- Compression is decided per photo rather than by one global quality setting, which is what the quality detector exists to do.Developer-stated
- The paid licence is a one-time purchase with no subscription, and covers three Macs on the Pro tier.
- Runs natively on both Apple Silicon and Intel Macs from a single universal build.
- Optimises in place from Lightroom, Photoshop and Capture One on the higher tiers, avoiding an export-and-reimport cycle.
Trade-offs
- The free tier stops at 50 images a day and covers one device, which is not enough for a working photographer.
- Only JPEG and HEIC are supported; other image formats need a different tool.
- A licence includes only one year of free updates, so the purchase is not permanent access to new versions.
- Beamr states two different compression figures — up to 80% on the technology page and up to 70% on the pricing page.
First-use experience
What the app asks of you when you set it up. Only established facts appear here; anything we could not confirm is left out rather than guessed at.
- Installation
- Download the disk image from jpegmini.com and drag JPEGmini Pro into Applications. The current build is 4.5.1.82111.
- First launch
- The app starts in a full-feature trial for seven days. When the trial ends it continues on the free tier, which allows 50 images a day on one device.
- System integration
- Images can be dropped onto the app or optimised in place from Adobe Lightroom, Adobe Photoshop and Capture One using Beamr's plugins, which are sold with the Pro + Plugins tier and above.
- Apple Silicon

What it does
JPEGmini re-encodes JPEG photographs so they take up less space. It is not a converter and not an editor: the output is still a baseline JPEG, which is what lets the result open in any browser, photo app or device that already reads a JPEG. What changes is how much information the file carries.
The method Beamr describes has two parts. An image-quality detector models the human visual system to work out how far a particular photograph can be pushed before the change becomes visible, and an encoder then adapts the JPEG encoding to that photo rather than applying one quality setting across a batch. The practical consequence is that a flat, low-detail image and a detailed portrait are not treated the same way.
Beamr claims reductions of up to 80% — five times smaller — on its technology page, while its pricing page says up to 70%. Both figures are first-party and they do not match. The saving is in any case image-dependent, so neither number describes what a given photo will do.
What it costs
The app is a one-time purchase with a free tier rather than a subscription. Free gives you 50 images a day on one device after a seven-day full-feature trial, and video only during that trial. Pro is $59 and lifts the cap, adds H.264 and H.265 video compression and resize-and-export, and covers three devices. Above that, Pro + Plugins at $89 adds the Lightroom, Photoshop and Capture One plugins, Pro + Automations at $99 adds watch folders and background processing, and the Complete Bundle at $129 includes everything.
Every tier includes one year of free updates. That is worth reading carefully before buying: a licence is not permanent access to future versions, only to the version you bought plus a year of releases.
Formats and where it fits
The scope is narrow by design. JPEG and HEIC in, JPEG out, plus H.264 and H.265 video on the paid tiers. PNG, WebP, GIF and SVG are not handled — for those, ImageOptim or Zipic are the tools to reach for, and for video in general CompressO or HandBrake will do more.
Where JPEGmini is strongest is in a photography workflow. The plugins let Lightroom, Photoshop and Capture One optimise in place, so the file never has to be exported, optimised and reimported. The Automations tier extends that to a watch folder, so a delivery gallery can be optimised as it is written.
The desktop app should not be confused with JPEGmini Cloud, which is Beamr’s browser-based gallery product sold separately on a subscription.

Questions about JPEGmini
Is JPEGmini free?
There is a free tier, but it is limited to 50 images a day on one device and only covers video during the initial seven-day trial. Unlimited images and video require a one-time purchase, with Pro at $59.
Is JPEGmini a subscription?
No. The desktop tiers are one-time purchases. Each includes one year of free updates, so a licence buys the app as it stands plus a year of new versions.
How much smaller does JPEGmini make a photo?
Beamr claims reductions of up to 80%, or five times smaller, on its technology page, and states up to 70% on its pricing page. The saving depends on the image, since compression is decided per photo.Developer-stated
Does JPEGmini change the image format?
No. It recompresses within baseline JPEG, so the output is still a JPEG that any browser or photo app can open. HEIC files are converted to JPEG as part of the pass.Developer-stated
Does JPEGmini handle PNG or WebP files?
No. The app works on JPEG and HEIC images and on H.264 and H.265 video. Other formats need a different optimiser.
Which macOS version does JPEGmini Pro need?
Version 4.5.1 declares a minimum of macOS 13.5. It is a universal build, so it runs natively on Apple Silicon and Intel Macs alike.
Competitors
Direct competitors: overlapping features aimed at the same users.
ImageOptim
Compress images and remove EXIF information.
Both shrink JPEG files on macOS, but JPEGmini is a closed-source commercial product with a per-day free quota while ImageOptim is free and open source.
Zipic
Batch image compression tool with presets and automation.
Both are Mac image compressors with paid upgrades, but Zipic covers PNG, WebP and HEIC broadly while JPEGmini concentrates on JPEG and video.
CompressO
Free, open-source video and image compressor for macOS.
Both reduce image file sizes locally, but CompressO is free and open source under AGPL-3.0 while JPEGmini is a paid commercial product from Beamr.
TinyPNG4Mac
Open-source tool to compress images.
Both are image optimisers aimed at web and design work, but TinyPNG4Mac sends files to an online service while JPEGmini processes them on the Mac.
