PNG to JPG Converter
PNG screenshots are sharp, lossless and frequently far too large to email. Converting to JPG typically cuts the file to a fraction of its size while keeping a photograph looking effectively identical. Choose a quality level, pick what replaces any transparency, and download the result. The image is processed in your browser and never uploaded.
How to convert PNG to JPG
- Drop your PNG files into the box above, click to browse, or paste an image with Ctrl+V.
- Adjust the quality, background or output size if you need to. The defaults are already sensible.
- Click Convert and download your JPG files, one by one or as a single ZIP archive.
Why convert PNG to JPG
The usual trigger is a limit somewhere: a 5 MB attachment cap, an upload form that rejects the file, a website that loads slowly, or a phone running out of space. PNG never discards data, so a photograph stored as PNG can easily be ten times the size of the same image as JPEG with no visible benefit, because photographic detail is exactly what lossless compression is worst at handling. JPEG was designed for that content and handles it far more efficiently. The conversion is also a compatibility move for print services and older systems that still expect a JPEG. The trade is permanent: transparency is lost, and the discarded detail cannot be recovered afterwards.
Your files stay on your device
Conversion happens entirely inside your browser using standard web technologies. Nothing is uploaded, nothing is stored, nothing is logged. You can open your browser network inspector during a conversion and watch it stay completely silent.
About PNG Image
PNG, short for Portable Network Graphics, was published in 1996 as a patent-free replacement for GIF and has been the default lossless image format of the web ever since. It stores pixels exactly as they were written, so text stays sharp, flat colour stays flat, and repeated editing never degrades the image. Its alpha channel carries 256 levels of transparency, which makes it the standard choice for logos, icons, screenshots and interface assets. The cost is file size: because nothing is discarded, a photograph saved as PNG is routinely four to ten times larger than the same photograph saved as JPEG or WebP.
- Standardised by the W3C in 1996 and supported by every operating system, browser and image editor.
- Lossless: re-saving a PNG a hundred times produces a pixel-identical file every time.
- True 8-bit alpha channel, so edges and soft shadows blend cleanly onto any background.
- Ideal for screenshots, logos, line art and anything containing text; a poor choice for photographs.
- Cannot store animation. APNG exists but is a separate extension with uneven support.
About JPEG Image
JPEG, almost always seen with the .jpg extension, has been the standard format for photographs since 1992. It compresses by discarding the detail the human eye is least likely to notice, which makes photographic files dramatically smaller at a quality setting most people cannot distinguish from the original. Practically every device, application, printer and web form accepts JPEG without question, which is why it remains the safest format to hand to someone else. It has two firm limits: no transparency at all, so transparent areas must be flattened onto a solid colour, and lossy compression, so every re-save of an edited JPEG throws away a little more detail.
- Released by the Joint Photographic Experts Group in 1992 and still the most widely supported image format in existence.
- Quality is adjustable from 1 to 100; above roughly 85 the visual gain is hard to see while the file keeps growing.
- No transparency support whatsoever, which is why transparent images need a background colour first.
- Generational loss is real: opening, editing and re-saving the same JPEG repeatedly degrades it visibly.
- The safest choice for email attachments, print submission and any upload form with a strict format list.
Frequently asked questions
How much smaller will the JPG actually be?
For photographs, expect roughly 5 to 15 times smaller at quality 90. For screenshots, flat-colour graphics and line art the saving is much smaller, and the JPEG may even look worse than the PNG, so those are usually better left alone.
My PNG logo has a transparent background. What will it look like as a JPG?
Transparency is replaced with a solid colour, white by default. This is the single most common surprise in this conversion: many tools silently use black and turn a dark logo into an unusable black rectangle. Here the background is always explicit and you can change it before converting.
What quality setting should I use?
Between 85 and 92 for anything important. The default of 90 is a good balance. Going above 95 inflates the file substantially for a difference almost nobody can see.
Will the text in my screenshot still be readable?
At quality 90 it is usually fine, though sharp text on flat backgrounds is the hardest case for JPEG and you may see faint haloing around letters. For screenshots that contain a lot of small text, keeping the PNG is the better choice.
Can I convert the JPG back to PNG to recover the original quality?
No. Converting back produces a valid PNG, but it preserves the compressed result, not the detail JPEG discarded. Keep the original PNG if you might need it again.
