Why this works well
- Meaningfully smaller files than PNG at the same visual quality — a real page-speed win
- No separate converter site — the conversion happens on the way to your drive
- Keeps transparency (alpha channel) — WebP supports it the same way PNG does
- Converts on the way to your drive — the WebP lands ready to serve, no download-and-reupload
- Choose smaller, balanced or best quality with the optimization control
- Runs server-side in a streaming pipeline — batches don't tie up your device
How to do it
- Connect a destination cloud (Google Drive, Dropbox, or S3-compatible storage).
- Upload your PNG files or transfer them from a connected drive.
- Pick WebP as the convert outcome.
- We stream the converted WebP into your drive, ready to serve or link to.
PNG vs WebP at a glance
How the conversion works
SaveToDrive re-encodes the PNG as WebP on a background worker and streams the result straight into your connected drive. Transparency is carried across, and the optimization control lets you pick how aggressively to compress — smaller, balanced or best quality.
The image is processed in memory as it streams through to your drive; nothing is written to a disk we keep. Because WebP is smaller than PNG at equivalent quality, the same images load faster when served from a website — a direct Core Web Vitals win.
Good to know
A few details worth having up front:
- Transparency (alpha) is preserved
- Pick smaller / balanced / best quality with the optimization control
- Convert a single image or a whole batch in one job
- Need even smaller files? PNG → AVIF is available too
FAQ
Does WebP keep PNG's transparency?
Yes — WebP supports an alpha channel just like PNG, so transparent backgrounds are preserved.
Will every browser display WebP?
All modern browsers support WebP natively. If you need to support very old browsers, keep a PNG fallback.
Is PNG → WebP available on the free plan?
Yes. Image converts are included on the free tier within your transfer quota.
How much smaller will my files actually get?
WebP is typically 25–35% smaller than PNG at equivalent visual quality, though the exact saving depends on the image. Photographic and detailed images usually shrink the most; simple flat graphics less so.
Is WebP lossy or lossless — will my image degrade?
WebP supports both. SaveToDrive uses a high-quality encode by default; use the optimization control to trade a little more size for a little more quality, or the reverse. Transparency is preserved either way.
Can I convert a batch of PNGs at once?
Yes — upload or transfer the batch and pick WebP once. Each file is converted as it streams into your drive, so one large image doesn't hold up the rest.
