Everything you need to make images smaller.
One native app for the whole job: lossless compression by default, modern formats, conversion, reusable profiles, and automation — all 100% on your Mac.
Lossless by default
ImageForge rewrites your images smaller without ever touching quality — using the best lossless tool for each format. Lossy is always an explicit, informed choice, never a silent default. Originals are handled exactly the way you tell it to.
Modern formats & RAW
PROGo beyond the classics. Compress and convert to WebP, AVIF and HEIC — with control over quality, effort and bit depth — and import RAW captures to convert them into shareable formats.
Reusable profiles
PRODial in per-format settings once, save them as a named profile, and reuse across every batch. Export and import profiles to share a house style across a team.
Format conversion
Turn a folder of PNGs into WebP, or HEIC into JPEG, with clear output naming and an honest signal of when a conversion is lossy versus lossless.
100% on your Mac
Nothing is ever uploaded. No account, no cloud, no telemetry. The Rust engine runs entirely on-device, so sensitive images never leave the machine — and it works fully offline.
Watch folders & automation
PROSet a folder to watch and ImageForge compresses every file the moment it lands — no clicks. A menu-bar item keeps quick actions one shortcut away, so optimizing becomes part of your workflow.
Seven formats. One engine.
Everything in Free. What Pro adds.
ImageForge is free and fully local. ImageForge Pro is a one-time purchase — no subscription — that unlocks modern-format output, RAW, unlimited custom profiles and automation.
One-time purchase, not a subscription. Everything stays 100% on your Mac in both tiers.
As polished as ImageOptim — more capable.

Questions, answered.
Does compressing reduce image quality?
Not by default. Lossless mode produces a pixel-identical image at a smaller size. If you choose a lossy profile, you decide the quality — with a live preview before anything is written.
Are my images ever uploaded?
Never. All processing happens on your Mac with a local engine. There is no cloud, no account and no telemetry, and the app works completely offline.
What happens to my originals?
Whatever you choose: overwrite in place, keep a copy with a -min suffix, or write to a separate folder. ImageForge never destroys an original without explicit consent.
What is free versus Pro?
Free covers lossless JPEG/PNG/GIF/WebP/SVG, basic lossy, batch and metadata stripping. Pro ($24.99 once) adds unlimited custom profiles & per-format control, AVIF & HEIC output, RAW import & conversion, and watch folders with a menu-bar item.
