How do I convert PPTX to PNG?

Add your PPTX file to the upload area above, then press Convert. The PNG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to PNG reduce quality?

The result is a reconstruction rather than a perfect copy. It is genuinely useful for reading and reuse, but review it before relying on it for anything important.

How large a file can I convert?

Up to 150 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

PPTX and PNG explained

PPTX is PowerPoint's modern format — a ZIP of XML describing slides, shapes, positions, animations and embedded media.

PNG is a lossless raster format built to replace GIF. It stores every pixel exactly as given and supports a full 8-bit alpha channel, which means genuine partial transparency rather than the single transparent colour GIF offers.

Where PPTX files come from: PowerPoint, Google Slides exports and Keynote exports.
Where PNG is used: Screenshots, exported logos and UI assets, and anything designed rather than photographed.

PPTX vs PNG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

PPTX compared with PNG
Property	Source	Target
Compression	Lossless	Lossless
Transparency	—	Yes
Animation	—	No
Introduced	2007	1996
Browser support	PowerPoint, Keynote, Google Slides, LibreOffice.	Universally supported.

PPTX is stronger at: Fully editable slides. Supported by PowerPoint, Keynote, Google Slides and LibreOffice. Holds animations, transitions, speaker notes and embedded media.
PNG is stronger at: Completely lossless — re-saving never degrades the image. Full alpha transparency, including soft edges and shadows. Sharp text and hard edges stay sharp.

Why convert PPTX to PNG?

People make this switch when they run into the limits of PPTX: sending a final deck where layout must be guaranteed — use PDF. PNG is the better fit when the image has transparency, text, screenshots, logos, or you need an exact pixel-for-pixel copy.

PPTX limitations that prompt the switch: Fonts and layout can shift between applications. Large when it contains video. Not a reliable final-delivery format.
What you give up: Much larger than JPEG or WebP for photographic content. No animation in practice (APNG exists but support is inconsistent).

Does converting PPTX to PNG reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

Converting a JPEG to PNG does not improve its quality. It freezes the image exactly as it already is, artefacts included, in a larger file.
