PNG to JPG Converter — Free, Private, No Upload
Shrink heavy PNG screenshots and exports into lightweight JPGs, right on your device. Nothing is uploaded, and there are no limits or signups.
Converting PNG to JPG is almost always about size. A screenshot, chart or export saved as PNG can be several times larger than the same image as a JPG, and email forms or chat apps often choke on big files. JPG shrinks them dramatically at a quality the eye can't tell apart — the one catch is that any transparent areas are filled with a solid background.
How to convert PNG to JPG
- 1 Drop your PNG files into the box above, or tap to pick them from your phone or computer.

- 3 Download each JPG, or grab them all at once as a .zip. Nothing ever left your device.
Yes — because nothing is uploaded.
Most converters send your photos to a server you know nothing about. Filexum can't, because it never asks for them: the conversion runs inside your browser, on your own device. You don't have to take our word for it — open your browser's Network tab and watch it stay empty, or turn off Wi-Fi and convert anyway.

Why PNG?
PNG arrived in 1996 as a free, patent-unencumbered image format, and it does something JPG can't: it is lossless. Every pixel is preserved exactly, and it supports full alpha transparency — which makes it the go-to format for screenshots, logos, diagrams and any image with sharp edges or text.
That perfect quality has a cost in size: a photographic PNG can be several times larger than the same picture as a JPG. If you want a pristine, editable copy of a HEIC photo — or you need transparency — PNG is the right target. For small, shareable files, JPG or WebP will serve you better.
Why JPG?
JPG (also written JPEG) has been the common language of digital photos since 1992. Every phone, browser, printer, TV and photo kiosk on the planet reads it, which is what makes it the safe choice whenever a picture just needs to open — on a friend's Windows laptop, an older website's upload form, or an email attachment.
It uses lossy compression, so pushing the quality very low can soften fine detail. At a sensible quality the difference is invisible to the eye, and you walk away with a file that works absolutely everywhere. This converter defaults to a high-quality JPG and lets you preview the result before you download.

PNG to JPG — frequently asked
Are my PNG files uploaded anywhere?
No. The conversion runs inside your browser, on your own device — nothing is sent over the network, not the file, its name or a hash. It works with Wi-Fi turned off.
How much smaller will the JPG be?
For photos and detailed screenshots, JPG is often several times smaller than the PNG. Flat graphics with few colours save less. You can preview the result before downloading.
What happens to a transparent background?
JPG can't store transparency, so any see-through areas are flattened onto a solid background. If you need to keep transparency, convert to WebP instead of JPG.
Will I lose image quality?
JPG uses lossy compression, so there is a small quality cost — invisible at the default setting for most images. Lower quality means a smaller file; the slider and preview let you choose.
Is this PNG to JPG converter free?
Yes — free, with no signup, ads or watermark, and no limit on how many files you convert beyond your device's memory.
Can I convert many screenshots at once?
Yes. Drop in a whole batch of PNGs and download every JPG together as a single .zip.
