Saved Compression Presets — Free, Fast & Private
If you compress images regularly, you have a workflow: a target file size, a preferred format, a quality level, maybe a watermark for client work, and a filename pattern that fits your project. Every batch needs the same settings. Saved presets bundle that whole stack into a one-click button.
Real examples: a photographer's "Instagram-ready" preset is 1280px max, WebP, 80% quality, no watermark, named {name}-instagram.webp. A web developer's "responsive set" preset is 4 sizes × 4 formats (AVIF, WebP, JPG, PNG), max quality 85%, named hero-{width}.{ext}. A content writer's "blog hero" preset is 1920×1080, WebP, 70%, with a subtle bottom-right watermark.
What can a preset hold?
- Max width (or any of 1920/1280/800px presets)
- Output format (JPG, PNG, WebP, AVIF)
- Quality preset (Gentle, Smart, Tiny, Auto, or a numeric quality)
- Pro fan-out: extra widths and extra formats for responsive sets
- Watermark settings: text, position (one of 9 anchors), opacity, scale
- Custom rename template
- Advanced codec settings: JPEG chroma subsampling and per-format quality overrides (applied to every output in that format)
Presets live on your device
Saved presets are stored in this browser's localStorage. No account needed, no server-side storage — which is the same privacy posture as the rest of MiniPx, and it comes with a real trade-off worth stating plainly: clearing site data wipes your presets, and there is no export, no import, and no sync between browsers or devices. A preset is a convenience that lives where you made it. Note the settings down somewhere if one took you a while to tune.
Pairs well with
The responsive image generator — bundle the 4×3 size×format matrix into one preset. Bulk rename templates — your preset includes the template too. Watermark tool — your preset stores the watermark configuration.
