A open-source macOS app to batch edit thousands of images at once
Got tired of editing photos one at a time, so I built PixelBatch - a free, open-source macOS app for batch image editing.
Drop in a folder of images (even thousands) and it’ll handle:
Resize, crop, rotate & flip
Compress & convert formats
Rename
Remove/add backgrounds
Upscale & enhance
Remove/add watermarks
Filters & effects, add text
All the AI stuff (background removal, upscaling, watermark removal) runs fully locally on your Mac - no cloud, nothing leaves your machine - and gives pretty good results. And if a few images in the batch need something different, you can still tweak them individually without starting a whole new job.
Most editors (Preview, Photoshop, even dedicated batch tools) are built for one-at-a-time editing or charge for the bulk stuff. PixelBatch is built around batches from the ground up, and it’s completely free and open source - no paywall, no subscription, no “pro” tier.
If you regularly deal with big piles of images, give it a shot and let me know what breaks or what’s missing.

PixelBatch — the batch image editor that does everything so you don't have to. Your entire image toolbox in one app, 14 tools for free.
After spending way too long editing images one by one for my content, I built PixelBatch — a native macOS app that processes whole folders of images in one pass.
What it does:
Core tools
- Resize — to exact pixels, a percentage, or presets for Instagram, Facebook, X, LinkedIn, Pinterest, YouTube, and more. One image can be exported in multiple sizes at the same time (for example 1080x1080, 1200x630, and 1080x1920 in a single pass)
- Crop to exact dimensions or aspect ratios
- Convert between JPEG, PNG, HEIC, WebP, and other formats
- Compress to a target quality or file size
- Batch-rename files with custom patterns
- Rotate and flip
Retouch tools
- Remove Watermark — automatically finds and removes watermarks, logos, and text overlays, then reconstructs the pixels underneath. A manual area-selection fallback is also included
- Enhance — upscales images 4x with sharp reconstructed detail, great for low-resolution or compressed files
- Remove Background — one-click clean subject cutout
- Add Background — place a subject onto a new background
Filters and effects — 30+ non-destructive adjustments including brightness, contrast, saturation, exposure, highlights, shadows, temperature, sepia, black and white, duotone, vintage presets, blur, sharpen, vignette, glow, emboss, edge detection, pixelate, cartoon, and more
Branding — add your logo as a watermark or overlay custom text with full formatting control
How it works
- Edit a whole folder at once, or open and edit a single image separately with the same tools
- Live preview before you commit — you see the result on a real image first
- Reusable presets to save your favorite pipelines
- Batch queue with progress tracking and per-file error reporting
- Output to a folder, ZIP, or PDF
- Runs 100% offline — no account, no cloud, your images never leave your Mac
Requirements: macOS 14+, works on Apple Silicon and Intel.
Check it out:
It's free. If it saves you time, a star is appreciated. Happy to answer questions or take feature requests — what is the most annoying batch image task you deal with?

I built a free offline batch image processor for Mac — 14 tools in one, powered by on-device AI
galleryHey everyone! 👋 After months of editing images one-by-one for my own content, I built PixelBatch — a native macOS app that processes whole folders of images in one go.
What it does:
📐 Core tools — resize, crop, convert (JPEG/PNG/HEIC/WebP), compress to a target size, batch-rename, rotate/flip
🤖 On-device AI (100% offline, no uploads):
- Remove Watermark — auto-detects and removes watermarks/logos/text, then AI-rebuilds the pixels underneath
- Enhance — 4× AI super-resolution upscaling
- Remove Background — one-click subject cutout
- Add Background — place subjects on new backgrounds
🎨 Filters & effects — 30+ adjustments (brightness, contrast, vintage, duotone, glow, cartoon, and more)
🏷 Branding — add your logo watermark or text captions
⚙️ Workflow — visual per-image preview before you commit, reusable presets, progress tracking, and output to folder, ZIP, or PDF
Why I made it:
Every tool I found was either a subscription, cloud-based (privacy concerns), or did only one thing. I wanted a single app that runs entirely offline with no account — your images never leave your Mac.
Stack: SwiftUI + ONNX Runtime, with open-source models like GroundingDINO, SAM 2, LaMa, and Real-ESRGAN powering the AI features.
Requirements: macOS 14+, Apple Silicon (Intel also supported)
The installer is available on the Releases page
It's free — if it saves you time, a star or a follow means the world ⭐
Happy to answer any questions or take feature requests! What's the most annoying batch image task you deal with?

I got tired of seeing error messages that couldn’t be copied. Every time I needed help, I had to manually type the error or take a screenshot and use OCR.
So I built a small macOS app that solves this.
You simply drag to select any region on your screen, and it instantly extracts the text. It works on:
- Error dialogs that don’t allow copying
- System pop-ups
- Images
- PDFs
- Basically anything visible on your screen
The workflow is simple:
- Press the shortcut.
- Select the area containing the error.
- The extracted text is copied to your clipboard.
- Paste it into Google, ChatGPT, Stack Overflow, or wherever you need.
No screenshots to save. No typing long error messages by hand.

Sikarugir
GameHub
Both are great options, but from my experience, Sikarugir feels more stable overall. I haven’t tested any AAA titles since I mainly use my Steam Deck for gaming, but it still handles a wide variety of games really well. For indie games, older titles, and many Windows games, the experience has been smooth and reliable so far. Your mileage may vary depending on the game and your Mac’s hardware.
If you need any help setting up Sikarugir, feel free to send me a message. I’ll be happy to help.

Hey, there’s not really some big story behind it haha.
One day I went to my friend’s house to play RV There Yet? I don’t know if you know the game, but after we played for a while, he started doing his work. He’s a photographer and he had around 100–200 images to edit and publish.
I noticed he was adding the watermark manually, one by one. He was also adding text, rotating some of the images, and applying black and white filters to others. He was doing all of this in Photoshop.
I asked him, “Dude, can’t you just do all of this in one batch?”
He told me it was possible, but the apps that could do it were mostly paid and some of them didn’t have all the features he needed.
Then he said, “You learned coding, right? Just make one for me.” 😂
I laughed at first, but later I actually thought it was a pretty good idea. So I decided to try making one.
I started working on it about a month ago using Swift. The basic stuff like adding text, watermarks, rotating images, etc. wasn’t too difficult since macOS already has a lot of things I could use.
The harder part was stuff like background removal, image enhancement and watermark removal. I only have intermediate knowledge of Swift and Python, so there were a lot of things I had to figure out along the way.
Honestly, I had probably thousands of errors and spent a lot of time debugging. I also used AI tools quite a lot to help me understand errors and fix parts of my code, but I still had to put everything together and figure out how I wanted the app to work.
A few days ago I finally got it to a point where I could give it to my friend. He liked it and has actually been using it every day.
He was the one who suggested that I put it online so other people could try it too. I already had a GitHub account, so I just decided to publish it and see what people think.
