Guide

How to use this WebP converter

The studio encodes each image with your browser's built-in WebP encoder, then shows the new size next to the old one.

Updated for 2026: batch conversion with progress and Cancel

1
Use the original
Convert from the best copy you have. Re-encoding an already squeezed JPG adds a second round of loss.
2
Test one first
Convert one typical image, open the before and after view, and adjust the quality before you run the batch.
3
Read the size change
Each row shows how much smaller (or larger) the WebP is. Keep the original if WebP doesn't help.
4
Grab them all
Download one WebP at a time, or every converted file in one ZIP named after today's date.

Guide

Getting small files that still look right

Four habits that keep quality up and file size down.

Quality

Find your number

Lower quality means smaller files and more visible blur or blocks. Check the before and after at full size.

Default 80
Lower for thumbnails
Higher for detail

Size

Resize before you convert

A 4000 pixel photo shown 800 pixels wide wastes bytes in any format. Resize it first.

Match the display size
Allow for sharp screens
Then convert

Transparency

Logos and cut-outs

WebP keeps transparent areas. Check soft edges in the comparison, since lossy WebP can blur them.

Transparency kept
Check soft edges
Try max quality

Source

Keep the originals

WebP is for publishing. Keep your JPG, PNG or design files to edit later.

Archive originals
Re-convert when needed
Don't edit the WebP

Quality guide

Quality slider or max quality?

Both make lossy WebP. The browser's canvas encoder has no lossless WebP option, so the studio doesn't promise one.

Slider, 10 to 100

The number goes straight to the encoder. Lower is smaller with more visible loss; higher is bigger and cleaner.

Max quality

Encodes at the top setting (1.0). Biggest files, closest to the original. Good for text, line art and UI shots.

Before and after

Open the comparison on any converted image to judge the result side by side.

Photos

Photos usually shrink the most, because lossy WebP is built for them.

Flat graphics

Logos and icons saved as PNG may shrink less, or even grow. The studio tells you which.

Animated GIFs

The canvas draws one frame, so an animated GIF becomes a still WebP.

Guide

How different people use WebP

Smaller images help anyone who puts pictures on a web page.

Site owners and bloggers

Lighter pages

Convert post images and banners so pages carry fewer bytes.

Typical setting: resize to the column width · quality around the default

Online shops

Product photos

Shrink a set of product shots in one batch and upload the ZIP's contents.

Typical setting: batch of 20 · compare one before and after

Developers

App assets

Turn PNG assets into WebP for a site or web app without installing a command-line tool.

Typical setting: max quality for UI · check transparency

Marketing teams

Campaign images

Make landing page and email header images lighter before they go live.

Typical setting: test one · then convert the set

Format facts

What WebP is, from Google's own docs

WebP is an image format made by Google. These are the facts the studio is built on.

Smaller files

Google's published comparisons.

Lossy: 25-34% smaller than JPEG
Measured at equal SSIM quality
Lossless: 26% smaller than PNG
Your images may differ

What it holds

One format for photos and graphics.

Transparency (alpha)
Lossy and lossless modes
Animation
Up to 16383 x 16383 pixels

Where it can't be made

Showing WebP and creating it are different things.

Safari can't encode WebP in a canvas
Same for Safari on iPhone and iPad
Firefox before version 96

Safari 14 and later show WebP images fine. Only creating them is the problem, so on Safari the studio stops and tells you, instead of saving a PNG with a .webp name. Use Chrome, Edge or Firefox to convert.

Guide

Keeping your image library light

Converting once helps. A routine keeps every new image small too.

1
Convert as you publish
Make WebP part of uploading: resize, convert, then add the image to your page.
2
Keep a quality note
Write down the quality that worked for photos and for graphics, so every batch matches.
3
Keep originals apart
Store originals in one folder and WebP files in another, so you never edit a compressed copy.
4
Recheck old pages
Your heaviest old images are often the easiest wins. Convert them in batches of twenty.

Pro tips

Pro tips for WebP conversion

Small checks that make a big difference to the result.

Compare at full size

Open the before and after and look at faces, text and edges, where loss shows first.

Resize first

Shrink oversized photos with the Image Resizer, then convert.

Watch flat graphics

If a PNG logo gets larger as WebP, keep the PNG. The row tells you.

Text needs quality

Screenshots with small text blur fast. Try max quality for them.

Convert on a computer

Big batches are faster on a laptop than on a phone, and Safari can't make WebP.

GIFs turn still

Animated GIFs come out as a single frame. Keep the GIF if the motion matters.

Same names, no clash

Two files called photo get photo.webp and photo-2.webp in the ZIP.

Metadata isn't copied

The WebP is a fresh encode from the pixels, so camera details from the original aren't carried over.

Pro tip: one test image saves a whole batch

Convert a single typical image, compare it at full size, and settle the quality. Then add the rest and convert them all with the same setting.

Which one

Smallest file, or closest to the original?

The slider trades a little quality for a lot of bytes. Max quality keeps detail and gives some of the savings back.

Photos · web pages

80default quality

Quality slider

Small files with loss most people won't notice in a photo. Lower it for thumbnails, raise it for hero images.

Best saving · check the comparison

Text · UI · line art

1.0encoder setting

Max quality

Closest to the original, still lossy. Use it where blur would show: screenshots, diagrams and sharp edges.

Best detail · bigger files

Verdict: use the slider for photos and max quality for anything with text or fine lines. Either way, check one image in the comparison before the batch.
