Will resizing reduce image quality?

Downscaling (making the image smaller) preserves quality very well — it's essentially throwing away pixels you didn't need. Upscaling (making it larger) can soften the image because the resizer has to invent pixels by interpolation. For natural-looking upscales beyond 2×, an AI upscaler is better than this tool. For all downscaling and modest upscaling (up to 2×), standard resampling produces clean results.

Will transparency be preserved?

Yes. WebP supports a full 8-bit alpha channel and the resize tool preserves it exactly — logos, icons, and PNG-style transparent assets stay transparent in the output WebP.

Should I use lossless or lossy WebP?

Lossless for graphics, screenshots, line art, logos, icons — perfect quality, often smaller than PNG. Lossy for photographs at quality 75-85 — typically 25-50% smaller than lossless WebP and visually indistinguishable. WebP's lossy mode is high quality even at quality 70-75; aggressive settings (50 and below) can show subtle softness on natural skin tones and gradients.

Can I resize animated WebPs?

Yes — animated WebPs resize frame-by-frame, with the same dimensions applied to every frame. The output is a smaller animated WebP. If you need a single still frame, see WebP to PNG.

Will the file size shrink in proportion to the dimension change?

Roughly yes, but not exactly proportional. Halving width × height = 1/4 the pixel area, which usually translates to ~70-80% smaller file (compression is more efficient at smaller sizes for natural images). Halving only one dimension cuts pixel count in half and file size by ~40-60%. Cropping is more aggressive than resizing for shrinking — see Crop WebP.

Can I batch resize many WebPs to the same size?

Yes — drop in entire folders. Same target dimensions apply to all. Each file processes in parallel on our servers and downloads individually or as a single ZIP. Useful for processing a website's image library to a new responsive breakpoint.

Should I resize before or after converting from another format?

Resize during conversion if both operations are needed — the conversion step has to re-encode anyway, so combining is more efficient. Examples: PNG to WebP lets you resize on the way out. If your source is already WebP, this resize tool is the right place.

What DPI should I pick?

For screen / web: 72 or 96 DPI. For inkjet draft prints: 150 DPI. For high-quality offset printing: 300 DPI. For fine-art prints: 600+ DPI. Note: DPI is metadata that tells the receiving software how big the image should print — it doesn't change the pixel dimensions. To actually change resolution, use the width × height fields.
