Mac
Batch-compress images & PDFs right on your Mac — fast, private, 100% on-device. No uploads, no accounts, no subscription. Free to use, with a one-time Premium unlock.
ImgOpt is the all-in-one image and PDF optimizer for Mac — fast, private, and 100% on-device. Drop in files or whole folders, pick a preset, and ImgOpt does the rest. Nothing is ever uploaded.
OPTIMIZATION ENGINES
Industry-standard engines under the hood: MozJPEG, ZopfliPNG, libwebp, and Apple's own ImageIO. Lossless modes keep your pixels bit-for-bit identical; lossy modes give you a quality slider for maximum savings. Every result is compared against the original — your files are never made bigger.
CONVERT ANYTHING
Read JPEG, PNG, HEIC, HEIF, TIFF, WebP, GIF, BMP, SVG and PDF. Convert to JPEG, PNG, HEIC, WebP or AVIF — or keep the original format and just optimize it in place.
FULL PDF TOOLKIT
- Compress PDFs with a lossless qpdf rewrite or lossy modes (Smaller / Balanced / Better).
- Export pages as images (JPEG, PNG, HEIC, WebP, AVIF) at your chosen DPI. (Premium)
- Combine images into a single optimized PDF, in your order. (Premium)
Password-protected PDFs are handled gracefully — unlock once, then keep or remove the encryption on the output.
PRECISE CONTROL
- Resize to fit-in-box or exact dimensions, set DPI, never enlarge by accident.
- Strip or keep metadata group by group — EXIF, GPS, IPTC, XMP, ICC and more. A one-click privacy profile drops location and personal tags.
- Filename templates with {name}, {date}, {width} tokens and zero-padded sequences. (Premium)
- Start from built-in presets — Compress for Web, Compress for Email, Max Compression — and save your own.
WATERMARK A WHOLE BATCH (Premium)
Drop in your logo and ImgOpt composites it onto every image as it's optimized. 9-point anchor, margins in pixels or %, size by long edge or max width/height, and full opacity control.
BUILT INTO macOS
- Finder right-click — "Open in ImgOpt..." and a quick Convert-to submenu.
- Shortcuts & App Intents for headless automation.
- Services menu and an imgopt:// URL scheme.
PRIVATE BY DESIGN
ImgOpt has no network access at all — it has no way to phone home. No accounts, no analytics, no tracking. Everything runs in the App Sandbox with the hardened runtime, touching only the files you choose.
PRICING
Free to use, with a single one-time Premium unlock — no subscription. Premium unlocks watermarking, PDF page export, combining to PDF, and filename templates, and stays unlocked on every Mac signed in to the same Apple ID, with Family Sharing.
