How the image converter works
Last updated 10 November 2026
Some sites accept only certain image types. Converting takes a few seconds.
How it works
- Choose the images and the format.
- Each picture is redrawn and saved in that format.
Why you might need another format
Websites and forms are fussy about image types. A job portal may want a JPEG, a design tool may want a PNG, and a website may prefer WebP for speed. Converting takes a few seconds and gives you a file the site will accept.
How the main formats differ
- JPEG: small files for photos, no transparency, some quality loss each time it is saved.
- PNG: sharp edges and transparency, ideal for logos and screenshots, larger for photos.
- WebP: usually smaller than JPEG or PNG at similar quality, but some older programs cannot open it.
What happens to transparency
A PNG can have see-through areas. JPEG cannot. When you convert a PNG with transparency to JPEG, the see-through parts are filled with white. If you need to keep the transparency, convert to PNG or WebP instead.
Quality and size
Each conversion redraws the picture, so converting between lossy formats can soften detail. If you only need a smaller file, use the compress tool. If you need a particular format for a form, convert once from your original and keep the original safe.
Your pictures stay with you
Conversion happens in your browser. The images are not uploaded and are not stored. If your browser cannot save a format, the tool says so rather than quietly giving you a different one.
Which format for which job
- Photos for email, forms and most uploads: JPEG.
- Logos, screenshots and anything with sharp lines or see-through areas: PNG.
- Web pages that need to load quickly: WebP, if the site and your visitors' browsers support it.
- Documents that ask for a PDF: use the images to PDF tool instead.
After converting
Open the converted picture to check it before you upload it. If it is still too big, run it through the compress tool. If it is the wrong shape, use the crop tool.
Several pictures at once
You can choose more than one picture and convert them together. Each result downloads with its new type, and the original names are kept so you can tell them apart. Check one or two of the results before you upload the whole set.
If something looks different
Colours can shift slightly between formats, and very sharp edges can look softer in lossy formats. If a result looks worse than the original, try the other format or a higher quality, always converting from the original file.
Things to watch
- Converting to JPEG removes transparency.
- Not every browser can save WebP. The tool tells you if yours cannot.
Like every tool on MoneyMzansi, this one runs entirely in your browser. There is no account, no upload and no sign-up. Your files are read and processed on your own device, and nothing is kept once you close the page.
