How to convert PNG to JPG

Two file formats cause the most upload headaches on Indian exam and document portals: PNG (common from screenshots and graphics tools) and HEIC (the default photo format on iPhones since iOS 11). Most portals only accept JPG/JPEG, so converting is usually the fastest fix rather than trying to change your phone's camera settings or find a workaround.

PNG to JPG — what changes

PNG is a lossless format, which is why it's larger than a JPG of the same photo — every pixel is stored exactly, with no compression trade-off. Converting to JPG applies compression, which is a real (if usually small and hard to notice) quality trade-off, but the resulting file is dramatically smaller and universally accepted. One thing to know: if your PNG has transparency (a see-through background, common in logos and graphics), JPG can't represent transparency at all — it gets filled with a solid colour, usually white, during conversion.

HEIC to JPG — why this one is so common

iPhones save photos as HEIC by default because it's roughly half the file size of an equivalent-quality JPG — great for phone storage, but a real problem the moment you need to upload to a portal, printer, or older Android device that doesn't recognise the format. Converting HEIC to JPG trades away some of that storage efficiency in exchange for near-universal compatibility.

Step-by-step

1. Open the Image Converter tool (or the dedicated PNG to JPG / HEIC to JPG pages).
2. Upload your file — the tool auto-detects whether it's PNG, HEIC or another format.
3. Select JPG as the output format.
4. Optionally set an exact KB target in the same step if your form also has a size limit.
5. Download the converted JPG.

Batch converting many files at once

If you have several PNG screenshots or a folder of iPhone HEIC photos to convert for the same form, the tool accepts multiple files in one go and converts each independently, delivering them together rather than one at a time.

What happens to transparency when a PNG becomes a JPG

JPG has no concept of transparency, so any transparent area in a PNG is filled with a solid color — usually white — during conversion, which is fine for a photo but can look wrong for a logo or graphic that was designed to sit on a colored background. If the transparent areas need to stay see-through, converting to JPG is the wrong move entirely, and the file should stay as PNG (or move to a format like WebP that also supports transparency) rather than being converted and then edited back afterward.

For an ordinary photograph that happens to be saved as PNG — a screenshot of a document, for instance — there is no transparency to worry about, and converting to JPG generally makes sense purely to get a smaller file size for the same visual content.
