What happens to transparency when converting PNG to JPG
JPG has no alpha channel, so transparent regions cannot survive the trip. This converter flattens transparency onto a clean white background — the standard expected by portals, marketplaces and print shops. If you need the transparency kept, stay with PNG and use the PNG compressor instead; converting is for when small size matters more than a clear background.
Why JPG is 5–10× smaller than PNG for photos
PNG stores every pixel losslessly, which photographs punish with huge file sizes. JPG discards micro-detail the eye does not notice, shrinking the same photo dramatically. At the default quality of 90, the converted JPG is visually indistinguishable from the source PNG at a fraction of the weight — ideal for email, forms and web pages.
When you should keep PNG instead
Screenshots full of small text, logos with hard edges, and any graphic needing transparency reproduce better as PNG — JPG compression smears crisp lines into faint halos. The rule of thumb: photographs and scans convert to JPG happily; interface graphics and line art stay PNG.
Convert PNG to JPG for Portal Uploads That Reject PNG
Many Indian government, exam and job portals whitelist only .jpg and .jpeg extensions — a PNG photo or signature fails validation before you ever see a size error. Renaming the extension does NOT work: the file's internal data is still PNG, and portal validators and document-verification systems read the data, not the name. Genuine conversion re-encodes the pixels as JPEG, which is what this tool does entirely in your browser — the file never uploads to any server. After converting, most portals also enforce a KB window; chain the result into our Image Compressor for exact targets, or the Signature Resizer if it's an exam signature with an official preset.
What Happens to Transparency — and Why the Background Turns White
JPG has no alpha channel, so transparent regions physically cannot survive the conversion. This tool flattens transparency onto a clean white background — the standard expected by portals, print shops and marketplaces, and the reason a converted logo or cut-out suddenly sits on white. If the transparency itself is the point — a logo going onto a colored website header, an icon for a presentation — do not convert: keep the file as PNG and shrink it with our PNG compressor instead. Convert when small file size and universal acceptance matter more than a clear background; that trade covers nearly every form-upload scenario.
The 5–10× Size Drop, Explained
PNG stores every pixel losslessly, which photographs punish brutally — a phone photo saved as PNG can weigh 15–25 MB where the same image as JPG weighs 2–3 MB. JPEG discards micro-detail below the eye's threshold, and at this tool's default quality of 90 the converted file is visually indistinguishable from the source at a fraction of the weight. The exception is graphics: screenshots dense with small text, logos with hard edges and line art reproduce worse as JPG, where compression smears crisp lines into faint halos. The rule of thumb — photographs and scans convert happily; interface graphics and line art stay PNG.
Frequently asked questions
What happens to the transparent parts of my PNG?
They are filled with white, the standard for documents and portal uploads. Keep the file as PNG if you need transparency preserved.
How much smaller will the JPG be?
Photographic PNGs typically shrink 80–90%. Graphics with few colors shrink less but still significantly.
Can I convert several PNGs at once?
Yes — up to 3 files at a time free. Larger batches with ZIP download are a Pro feature.
Is anything uploaded?
No. Conversion happens entirely on your device in the browser.
PNG ko JPG me kaise convert kare?
Drop the PNG in and download — conversion runs entirely in your browser, and transparent areas are filled with white as portals expect.
File ka naam .jpg karne se kaam chalega?
No — renaming the extension does not change the file's internal data, and portal validators read the data, not the name. Genuine conversion re-encodes the pixels as JPEG, which is what this tool does.
