One converter for every image format headache
Image formats are tribal: cameras speak JPG, designers trade in PNG, the modern web prefers WEBP, and every uploader, CMS and government form has its own opinion about which it will accept. The result is a constant low-grade chore — “please upload as JPG”, “PNG only”, “this image type is not supported”. This universal converter ends the chore: drop any mix of images, pick the target format, and download the converted files one by one or all at once. Conversion happens in your browser, so a folder of private photos stays private.
How to convert images
- Drag your images into the drop zone — any mix of JPG, PNG, WEBP and GIF.
- Choose the output format and, for JPG/WEBP, a quality level.
- Click Convert.
- Single files download automatically; batches list each result with its new size, plus a Download all button.
Knowing the formats: a 60-second field guide
JPG compresses photographs brilliantly by discarding detail your eye barely misses; it has no transparency and re-saving repeatedly degrades quality. PNG is lossless and supports transparency, making it the home format for screenshots, logos and graphics with text — at the price of large files for photos. WEBP is the modern all-rounder: typically 25–35% smaller than JPG at the same visual quality, with transparency support, ideal for websites — its only weakness is the occasional elderly software that can't open it, which is precisely why “WEBP to JPG” is one of the most-used conversions on the internet.
What happens during conversion
Each image is decoded to raw pixels and re-encoded in the target format — a true conversion, not a renamed file extension. Converting to JPG flattens any transparency onto a white background (JPG has no alpha channel). The quality slider applies to lossy targets: 92% is visually indistinguishable from the source for almost all content, while 75–85% buys real file-size savings for web use. PNG output ignores the slider because PNG is lossless by definition.
Batch tips
- Mixed inputs are fine: a batch of JPG + PNG + WEBP converts in one pass to a single target format.
- Names are preserved — only the extension changes, so files stay recognisable.
- Going PNG → JPG for size? Consider WEBP instead: smaller than JPG with the same workflow.
- Check one file first when quality matters; settings apply to the whole batch.
Whatever the uploader on the other side demands, you're now three clicks from compliance — with no software installed and no images leaving your machine.

Frequently asked questions
Which format should I choose for a website?
WEBP, almost always — it's 25–35% smaller than JPG at equal visual quality and supports transparency. Keep JPG for maximum compatibility with old software, and PNG for screenshots or graphics that must stay pixel-perfect.
Why did my transparent logo get a white background?
You converted to JPG, which has no transparency support. Convert to PNG or WEBP instead and the transparent areas survive intact.
Does converting reduce image quality?
Converting to PNG is lossless. Converting to JPG/WEBP at the default 92% quality is visually identical to the source. Repeated JPG→JPG cycles do accumulate loss, so always convert from your best original.
Can I convert HEIC photos from an iPhone?
Browsers can't decode HEIC directly. Set your iPhone camera to “Most Compatible” (JPG), or export/share the photo as JPG first — then any conversion here works.
