Image format converter — JPG, PNG & WebP for CMS, email, and fast pages

This free online image format converter lets you switch between JPEG, PNG, and WebP without installing Photoshop or ImageMagick. Pick an output codec, tune JPEG and WebP quality, preview the result, then download a new file or copy the image to the clipboard. Everything uses the Canvas API in your browser—useful when a CMS only accepts JPG, marketing needs email-safe JPEGs, or engineering wants WebP for LCP without a build pipeline. Combine this page with the image compressor, image resizer, and image to Base64 tools from our file and data tools catalog.

Processing stays in your browser. JPEG flattens transparency onto white. Clipboard image paste depends on the app you paste into.

Why teams convert image formats (JPG vs PNG vs WebP)

JPEG is the default for photographs and many email templates because files stay small and every client renders it. It does not store transparency, so logos with alpha are usually exported as PNG. PNG is lossless and supports alpha, which makes it ideal for UI screenshots, icons on arbitrary backgrounds, and crisp text in graphics. WebP combines lossy and lossless modes with often smaller bytes than JPEG or PNG—popular for responsive sites and CDNs when you control formats end-to-end. This JPG PNG WebP converter helps you align exports with each channel without leaving the browser.

Searchers look for convert PNG to JPG online, WebP to PNG, or change image format for WordPress. The workflow is the same: decode locally, re-encode to the target MIME type, and download. When you only need to inspect dimensions or EXIF before converting, open the image metadata viewer first, then return here for the actual transcoding step.

How to use this image format converter (step by step)

  1. Click Upload image or drag a raster file into the dashed drop zone. Common inputs include PNG, JPEG, WebP, and GIF frames the browser can decode.
  2. Under Output format, choose WebP, JPEG, or PNG. For JPEG or WebP, move the Quality slider to balance sharpness versus file size; PNG ignores quality because it is lossless.
  3. Compare Original and Converted preview, and read the output size line to see whether you saved bytes.
  4. Press Download to save .jpg, .png, or .webp beside your original basename, or use Copy image (with the copy icon) to paste into tools that accept clipboard images.

Transparency, email HTML, and CMS uploads

When you convert PNG to JPG, transparent pixels are composited on white so email clients and legacy CMS fields get a predictable matte. If you need a different background, export PNG or WebP instead, or edit in a design tool before converting. For vector logos, the SVG optimizer complements this raster workflow when SVG remains the source of truth.

Privacy and performance notes

Images never leave your tab, which matters for screenshots of staging environments or pre-release marketing assets. Very large bitmaps can stress memory; if the tab feels slow, use the image resizer to reduce dimensions before format conversion. To verify a downloaded file after handoff, the file hash checker computes MD5, SHA-1, and SHA-256 locally.

Frequently asked questions

Can I convert JPG to PNG or PNG to WebP in the browser?
Yes. This tool decodes your image with the browser’s built-in codecs, draws it to a canvas, and exports a new file in PNG, JPEG, or WebP. Conversion runs locally in your tab—no upload to a server.
Will transparency be preserved when I convert PNG to JPG?
No. JPEG does not support an alpha channel. The tool composites transparent areas on a white background before exporting as JPEG, which matches what most CMS and email tools expect when they ask for a .jpg.
Is WebP supported everywhere I need to ship images?
Modern browsers and many CDNs support WebP well for the web. Some older email clients still prefer JPEG or PNG. If a stakeholder requires a specific format, pick PNG for lossless graphics, JPEG for photos, and WebP when you want smaller files for responsive sites.
Are my photos uploaded to your servers?
No. FileReader and the Canvas API process the image only inside your browser. The download and optional clipboard copy use blobs generated on your device.
Why does my WebP or JPEG file size change when I adjust quality?
JPEG and WebP are lossy at most quality settings: lowering the slider removes more detail to shrink bytes. PNG is lossless for each export, so size depends on image complexity more than a simple quality dial.
What is the difference between this and the image compressor or resizer?
This page changes the file format (for example PNG to WebP). The image compressor focuses on shrinking bytes within a format, and the image resizer changes pixel dimensions. You can chain workflows: resize or compress first, then convert format if your CMS or email template requires it.
Can I copy the converted image instead of downloading?
Yes. After conversion, use Copy image to place the result on the clipboard (where the browser allows), for example to paste into design tools or chat. If clipboard image copy is blocked, use Download instead.
