Methodology + Sources
- Resolution choice (1080px wide): matches Instagram, Reddit, and TikTok native upload sizes to avoid platform recompression.
- Watermark placement (bottom right, 5% height): follows app-watermarking convention seen in Cal AI, Snapchat, and similar viral photo tools.

Frequently asked questions
Are my photos uploaded anywhere?+
No. Every part of this tool runs in your browser. Your photos never leave your device. The composite is generated locally on a canvas element and downloaded directly.
Can I add more than 2 photos?+
Yes, up to 4. Useful for multi-month progress timelines (week 0, week 4, week 8, week 12). Side-by-side layout works best for 2, stacked layout works better for 3 or 4 photos.
What file formats can I download?+
JPG (smaller, best for sharing on Instagram or Reddit), PNG (lossless, larger), and WebP (smallest file size, supported by all modern browsers).
What is the output resolution?+
Output is 1080 pixels wide for side-by-side and 1080 pixels per slot for stacked. This matches Instagram and Reddit upload sizes without forcing them to compress your photos.
Why is the Zealova watermark in the corner?+
We built this tool free for the fitness community. The small watermark helps other people find Zealova when you share your progress. You can crop it out, but please leave it on if you can. It is how we sustain free tools without a paywall.
