Frequently Asked Questions
Answers about ShareMint's features, data handling, and pricing.
Is ShareMint free to use?
Yes. Core features like SNS image resizing, focal point targeting, and ZIP batch download are completely free. Advanced features such as watermarks, filters, batch processing, and GIF anti-AI effects are available with the Pro plan ($3.99/mo).
Are my images uploaded to a server?
No. All image processing in ShareMint happens entirely in your browser. Your images are never uploaded to any server. Your privacy is fully protected.
Which platforms are supported?
ShareMint supports 14+ platforms including Instagram, X (Twitter), TikTok, YouTube, LINE, Facebook, Threads, Bluesky, Pinterest, LinkedIn, WordPress, note, and Hatena Blog. Preset sizes are kept up to date.
Can I use iPhone HEIC photos?
Yes. You can upload HEIC/HEIF images directly. They are automatically converted to JPEG in your browser — no pre-conversion needed.
What's the batch processing limit?
The Pro plan supports up to 50 images per batch. All selected SNS presets are applied with auto-crop and resize, and results can be downloaded as a single ZIP file.
Is watermarking free?
Watermarking is a Pro plan feature. It supports text, image (logo), and QR code watermarks with full customization of font, size, color, position, and opacity. 9-point positioning and tiled layout are available.
What are GIF anti-AI effects?
This feature exports images as animated GIFs with subtle pixel noise, watermark micro-shift, and hue shift — imperceptible to humans but effective at deterring AI training scrapers. Available on the Pro plan.
What output formats are supported?
The free plan supports JPEG and PNG. The Pro plan adds WebP, PDF, and GIF (with anti-AI effects). Output quality is fully adjustable.
Does it work on mobile?
Yes. ShareMint is fully responsive and works great on smartphones and tablets. It also supports PWA — add it to your home screen for an app-like experience.
What are template saves?
You can save frequently used preset combinations as templates. The free plan allows up to 3 templates; the Pro plan offers unlimited saves. Load your templates with one click to skip manual preset selection.
