How to use the Image Format Converter

1. Drop an image onto the panel or click it to browse. JPG, PNG and WebP files are all accepted as input.
2. Choose the output format from the Convert To menu.
3. Click Convert & Download. The converted file is saved straight to your device.

When to use it

Typical jobs: turning a WebP file a designer sent you into a JPG that an older CMS or a print shop will accept, converting a PNG screenshot into a smaller JPG for an email, or producing WebP versions of product photos so your web pages load faster. Because the conversion runs inside your browser, it is also the right choice for images you would rather not upload to a third-party service, such as ID scans or unreleased product shots.

What changes between the three formats

JPG compresses photographs well and produces the smallest files, but it has no transparency and every re-save loses a little quality. PNG is lossless and keeps transparent areas, so it is right for logos, icons and screenshots, and wrong for large photos, which balloon in size. WebP does both jobs in smaller files than either, but some older software, email clients and print workflows still refuse it. Converting to JPG from a PNG or WebP with transparency fills the transparent areas with a solid background, because JPG has no way to store them.

Worked example

A designer sends a logo as WebP and the print shop's upload form only takes JPG or PNG. Convert to PNG, not JPG: the logo has a transparent background and PNG keeps it. In the other direction, a 3 MB PNG screenshot pasted into a support email bounces for size; converted to JPG it is under 400 KB and looks the same on screen. And a set of product photos going onto a website converts to WebP for roughly a third smaller files than the JPG originals, with a JPG copy kept for the marketplace that does not accept WebP.

Common mistakes

• Logo to JPG. The transparency is gone and the edges pick up artefacts. PNG.
• Converting JPG to PNG to "improve" it. The quality lost in JPG does not come back; the file just gets bigger.
• WebP for email attachments. Several mail clients show it as an unknown file. JPG or PNG for anything sent to people whose software you do not know.

When this tool is the wrong one

It converts one file at a time and does not change dimensions. For a batch, or for resizing at the same time, the Bulk Image Resizer does both. HEIC from an iPhone, TIFF, SVG and PDF are not supported here.

Good to know

JPG and WebP are lossy formats, so converting to them trades a little detail for a much smaller file; PNG is lossless and keeps transparency. If you need to change the pixel size as well as the format, the Bulk Image Resizer linked below does both in one pass.
