Do I need to sign up?

No. Converting and downloading need no account. Signing in is only for saving the result to the cloud and continuing on another device.

Is the result watermarked?

No. Nothing is watermarked and there is no limit on how many times you convert.

Is my file uploaded to your servers?

No. The whole conversion happens in your browser. Open DevTools (F12) and watch the Network tab to check. The one thing that uses the network is the text-recognition engine for scans, downloaded once and only if you agree.

How big a file can I convert?

There is no limit. We no longer measure your file up front — that number was ours, not any device’s real ceiling. We just start; if this device genuinely cannot fit it, the browser says so and we pass on the reason, a way forward, and an event ID.

Does it work on a phone?

Yes, with the same features as on a computer. Very large files will simply take longer.

Will you start charging later?

It is free and unlimited today. We avoid absolute promises nobody can back, and there is no hidden sign-up wall or usage cap either.

Very tall images come back blank on mobile browsers, so each holds about 7 slides and the rest continue in the next.

Can I stitch other images?

This tool only stitches slides. For arbitrary images, use TutuEdit’s long-image tool.

Each slide is rendered 1920px wide, so text stays sharp.

PPT to Long Image — free, no watermark, no sign-up

Stack every slide of a PowerPoint vertically into one long image (with a 24px light-grey gap between slides) — easy to post or send, and people can scroll through without opening PowerPoint. Longer decks are split into several long images: mobile browsers have a hard limit on one image (about 7 slides at 1920×1080) and return a blank one beyond it, so the result says how many you got.
