Photo collage FAQ
How do I make a photo collage for free?
Open /images/collage/, drop your photos in, pick a template (for example 4 photos 2×2 or 9-photo Instagram grid), tweak the gaps and click "Download PNG". No registration is required and there is no watermark on the result.
How many photos can I add to a collage?
v0.5 supports up to 9 photos per collage — enough for an Instagram 3×3 grid. If you pick a 4-slot template, extras stay in the gallery underneath and you can swap them in with one click.
Are my photos uploaded to a server?
No. Convertilo processes every photo right in your browser using HTML Canvas. Images are not sent to a server, not stored and not shared with third parties — safe for personal shots and documents.
What file formats are supported?
Input: JPG (JPEG), PNG, WebP, GIF, BMP. Output: high-resolution PNG (up to 2160 px on the long side). PNG keeps maximum quality and is great for social media and print.
Can I make a before/after collage?
Yes. Pick the "Before & After" template — it splits the collage in two and adds BEFORE / AFTER labels over the photos. Great for beauty results, renovations, fitness transformations and portfolios.
Does it work on iPhone?
Open Convertilo in Safari or Chrome, tap the upload area and pick photos from your iPhone library. iOS auto-converts HEIC to JPG when picking from "Photos", so iPhone shots work out of the box.
