Convert PNG images to JPG with a white background
Choose JPG output when you need a JPEG file for a photo, document upload or compatible application. PNG-to-JPG conversion uses adjustable JPEG quality and keeps dimensions by default.
- Choose your PNG images. Check whether any have transparent backgrounds.
- Adjust JPEG quality and optionally resize large images.
- Convert, inspect the white background and fine detail, then download the JPG results.
What to expect
JPG has no transparent pixels. This converter fills transparent PNG areas with white before encoding. Text and logos may show JPEG artifacts; PNG or WebP can be a better choice when crisp edges or transparency matter.
Can I choose another background colour?
This version uses white for transparent areas and has no background-colour picker.
Will a PNG photo become smaller as JPG?
It often can, but not always. Compare the actual size and appearance rather than assuming the new extension means a smaller file.
Can JPG keep a transparent logo?
No. Use PNG or a transparency-supporting WebP output when the background must remain transparent.
HOW IT WORKS
How PNG to JPG conversion works
A new format means a newly encoded file. Here is what changes—and what happens to quality, dimensions and transparency.
How PNG becomes JPG
The browser decodes the PNG source to pixels and encodes a new JPG file. This changes the file’s actual contents, rather than just its extension. Dimensions stay the same unless resizing is selected. Conversion cannot recover detail already lost in the source.
What does encoding mean?
Decoding turns the bytes in an image file into pixels that a browser can display. Encoding turns pixels back into a file, using the rules of JPG, PNG or WebP. It is not encryption. Our compression and conversion tools decode locally, draw the image onto a canvas and call the browser’s canvas.toBlob encoder. The browser supplies the codec, so results can vary between browsers.
How JPG compression works
JPEG commonly splits image information into small blocks, uses a discrete cosine transform to describe patterns within them, then rounds transform coefficients in a step called quantization. Coarser rounding saves space but discards detail. The remaining values are efficiently coded into bytes. Our quality control is passed to the browser encoder; it is not a percentage of original detail retained or a guaranteed percentage reduction. Repeated JPG re-encoding can introduce additional artefacts.
What happens to quality and transparency?
JPG has no alpha channel. Transparent areas are placed on white before encoding. JPG can be useful for photographs, but text edges may show artefacts and the output is not guaranteed to be smaller.
Where processing happens
Your selected image is processed on your device, without an image upload. Canvas exports are new files and may change embedded metadata or colour information. Keep a master copy for archival work. Animated PNG and animated WebP are rejected; these tools handle static images.
How target-size compression works
Choose 100 KB, 200 KB, 500 KB or a custom decimal-KB limit. For JPG/WebP, the tool tries quality values from your selected maximum down to 10% and refines a successful bracket with a bounded binary search. When you explicitly allow smaller dimensions, it can also try up to eight downsizing steps. PNG ignores quality. Exact resizer dimensions are preserved. Only a measured output within the byte limit is marked Target met; otherwise the smallest tested candidate is marked Above target. This is a bounded search, not proof of a globally optimal result.
Metadata choice
Preserve supported metadata is the default: EXIF dates, camera and GPS fields are copied, with orientation reset after decoding and dimensions updated. PNG text/dates and JPG comments stay within their format. XMP, IPTC and original colour profiles are not transferred; embedded preview links are cleared. Retained metadata is included in target-size measurements. Remove metadata omits source metadata and disables the original-file fallback. Filesystem download dates are separate.

GOOD TO KNOW
A few small details.
Better images start with the right settings.
Which format should I choose?
WebP is a useful starting point for website photos and transparent graphics. JPG suits photos when you need a JPEG file; transparent areas become white. PNG uses lossless encoding and keeps transparency, but often creates larger files.
Will compression change image quality?
JPG and WebP use lossy compression: lower quality usually means smaller files and more visible changes. Use Compare to inspect your result. PNG encoding is lossless, but resizing still changes pixels. PNG conversion can increase file size. This tool uses your browser’s image encoders, so results can differ between browsers.
Why is my image already small?
If the output uses the same format and dimensions but is larger than the original, we keep your original file. Changing formats or dimensions can still create a larger result; the actual size is always shown. The quality slider doesn’t affect PNG encoding.
Are there file limits?
Add up to 100 static images, 50 MB per image and 200 MB of original files per batch. Each image must be within 40 megapixels and 16,384 pixels on either side. Animated PNG and WebP are rejected to protect their animation. GIF, SVG, HEIC and AVIF aren’t supported in this version. Large batches depend on your device’s memory.
Are my images uploaded or saved?
This tool processes selected images locally in this browser tab and doesn’t send image files to a server. Your site’s hosting, analytics or other plugins may separately collect normal website visit data. Download results you want to keep before clearing the list or leaving. Re-encoding generally removes file metadata; an original file kept because it was smaller retains its existing metadata. This isn’t a metadata sanitization tool.
