Manipulation, not editing
You’re not retouching — you’re resizing and compressing. Weppy does exactly that, without opening Figma or Photoshop.
v1.0 Manipulation, not editing
One app, dedicated to image optimization.
Huge files from a client? Skip the Figma tweaks and the TinyPNG upload. Resize, optimize, and ship — bulk optimize when the folder's huge.
macOS 10.15+
Free download
Email required
Skip cumbersome image workflows.
Weppy is a Mac-native app for image manipulation and optimization — not another editor. Drag in files, click once, get web-ready output. Fully offline.
Non-destructive
Originals stay untouched. Weppy writes new files where you choose — your source folder is never modified.
Smart resizing
Fit within bounds or force exact dimensions. Aspect ratios preserved and quality kept intact.
Native to macOS
No TinyPNG uploads, no daily caps. Everything processes on your Mac — offline, private, and fast.
Lossless & fast
Lossless by default. A whole folder in seconds — not an afternoon of export-and-upload.
AI settings help
Not sure what to pick? Describe your goal and Weppy suggests the right size and quality settings in seconds.
Smaller files. Zero round-trips.
Capabilities
Drop in a single file or entire folder.
Single hero image or a client’s entire asset dump — same queue, same one-click optimize. Running count and total size up front.
- Files and folders in one drop
- Unsupported files quietly skipped
- Per-file errors never abort the batch
Resizing
Smart resizing that keeps aspect ratio and quality.
Fit images inside a bounding box, or force exact dimensions with contain, cover and stretch strategies.
- Fit-within or forced-size modes
- Aspect ratio preserved by default
- “Only if larger” guardrail
Control, when you want it
A small-focussed featureset
Smart optimization
Standard, Smart, or Max — pick how hard Weppy works per format without leaving lossless behind.
Output your way
Keep the original format or convert everything to WebP, JPEG or PNG. Choose a destination, suffix and metadata handling.
Save your presets
Bundle your favorite settings into a named preset and reuse them — web exports, client handoffs, whatever you ship.
Tune the effort
Dial how hard the optimizer works, trading a little CPU time for the smallest possible files on big, important jobs.
Light & dark
Follows your system appearance automatically, with a manual override and a compact density mode for very large queues.
Reveal when done
Done optimizing? Jump straight to the output folder from the completion bar — every file, one click away.
How it works
Drop to optimized, in three steps.
1
Drop your images
Drag files or whole folders onto the window, or pick them with the file browser. Weppy queues everything up instantly.
2
Tune the settings
Set a max size, choose lossless or lossy, pick an output format. Or just leave the safe defaults exactly as they are.
3
Click optimize
Watch the savings roll in per file, then reveal the results in Finder. Originals stay right where you left them.
