How this tool works

Output format

Choose JPG, PNG, WebP, or Same as input. PNG is lossless; JPG/WebP use the quality slider.

Batch & ZIP

Select multiple files to convert them together and download a ZIP with per-file status.

JPG background & size

Set the color used to fill transparency for JPG, and an optional target file size for JPG/WebP.

Privacy & metadata

In-browser only; nothing is uploaded. Re-encoding through the browser canvas removes EXIF and other metadata.

WebP Converter in your browser

WebP Converter converts images in your browser and lets you choose the output format — JPG, PNG, WebP, or Same as input (which keeps JPG, PNG, or WebP and falls back to JPG for other formats). It is focused on WebP — convert images to WebP using the browser’s canvas encoder, or convert WebP files to JPG or PNG as a fallback.

Select multiple files to convert them all at once and download a ZIP, with a per-file status list that skips anything that is not an image and keeps going. For JPG output, pick the background color used to fill transparency; the quality slider applies to JPG and WebP only (PNG is lossless and ignores it). An optional target file size lets you aim for a size for JPG/WebP output, reported as under or over.

WebP Converter processes everything in your browser — nothing is uploaded. Animated GIFs are exported as a single still frame — animation, timing, and frames are not preserved by this canvas tool. Re-encoding through the browser canvas removes EXIF and other metadata.

How to use WebP Converter

  1. Upload one image, or select several, into WebP Converter — click, press Enter, or drag files in.
  2. In WebP Converter, choose the output format (JPG, PNG, WebP, or Same as input) and, for JPG, a background color; set the quality and an optional target size.
  3. Click Process and WebP Converter converts — a single file downloads directly, while multiple files are packaged into a ZIP with a per-file status list.
  4. Review WebP Converter’s result panel or per-file list — formats, dimensions, sizes, and how transparency was handled — then download.

Why use WebP Converter

Pick your format

JPG, PNG, WebP, or Same as input — convert to what you need, or keep the original format for a metadata strip or size change.

Batch to a ZIP

Convert many images at once and download a single ZIP, with a per-file status list and skipped non-images noted.

Honest quality & transparency

Quality applies to JPG/WebP (PNG is lossless); JPG output flattens transparency to your chosen color, reported in the result.

Private by design

Every conversion runs in your browser; nothing is uploaded.

Common uses for WebP Converter

Converting a batch

Drop a folder’s worth of images and get them all in one format as a ZIP.

Reducing file size

Convert to JPG or WebP and use quality or a target size to make smaller files.

Normalizing formats

Use Same as input to strip metadata or approach a size without changing the format.

Any-device conversion

Convert from a phone, tablet, or computer browser with files staying local.

Frequently asked questions

Are my images uploaded to a server by WebP Converter?

No. WebP Converter converts every file in your browser using the HTML canvas, and nothing is sent to imgtoolsbase or any server.

Can WebP Converter convert several files at once?

Yes. Select multiple images and WebP Converter converts them all and downloads a ZIP, listing each file’s result and skipping any non-image files with a note.

Does the quality slider affect PNG output in WebP Converter?

No. PNG is lossless, so most browsers ignore a quality value for PNG. In WebP Converter the quality applies to JPG and WebP output; the result panel shows whether quality was used.

What does "Same as input" do in WebP Converter?

In WebP Converter, it keeps the original format when it is JPG, PNG, or WebP — useful when you only want to strip metadata, normalize, or approach a target size; other formats fall back to JPG, and the result panel says so.

What happens to transparency when WebP Converter outputs JPG?

JPG cannot store transparency, so WebP Converter fills transparent areas with the background color you choose; PNG and WebP output preserve transparency when the source has it.

What if my browser cannot encode the WebP output mode I selected?

When you set the output to WebP, WebP Converter encodes with the browser’s canvas WebP encoder. On a very old browser without WebP support, that output mode stops with a clear error — switch the output format to JPG or PNG instead. WebP Converter offers quality-based WebP, not advanced encoder settings.
