PNG to JPG Converter
Convert PNG to JPG locally with Sharp. See output settings, step-by-step instructions, format limitations and common questions.
PNG to JPG
Convert a PNG image into JPG for an upload form, website or editing app that expects that format. The converter decodes the image and writes a new file rather than renaming the extension. JPEG uses lossy compression and fills transparent areas with white.
- Prepare a JPG copy for a service that does not accept PNG.
- Set an output width while retaining the original source file.
- Create a delivery copy with the settings your next app needs.
How to use PNG to JPG
Select your PNG files
Use Select File or drop supported PNG files into the upload area. Each file creates a separate JPG result. Check that the filename extension matches the contents and that the original opens correctly before adding a larger batch.
Choose the output settings
Open Options beside a selected file. Width, Quality are available for this PNG to JPG operation. Save options to apply them to that file; other files in a batch can use different settings.
Convert to JPG
Select Convert to add the files to the local queue. Files run one at a time, with real progress where the engine provides it. You can cancel a queued or running job and retry a failed result after correcting its input or settings.
Download and check the result
When a file is finished, use Download to save the JPG result. Use Download all for finished results on this converter page. Save downloads before the 30-minute temporary retention ends.
Understand the settings
- Width (pixels; 0 keeps original)
- Set the output width in pixels. Use 0 to keep the original width; proportions are retained. Default: 0.
- Quality
- Choose a value from 1 to 100. Higher values keep more detail and may produce larger files. Default: 85.
Choose settings for the destination
Start with a 2400-pixel-wide PNG image. Set Width to 1200 to create a narrower copy while retaining its proportions. Compare the default quality with a lower value if file size matters. Check the white background if the source contained transparent areas.
Check your result
Inspect small text, fine edges, orientation and transparency at the intended display size. Standard format-pair conversion uses the first frame or page and removes metadata. Use the dedicated animation tools for moving GIF/WebP/APNG, or metadata tools when inspection or removal is the specific task.

PNG to JPG: common questions
How do I convert PNG to JPG?
Choose your PNG files, review Options and the format notes, then select Convert. Download the finished JPG copy and check it in your destination application. Each input is processed independently; the original file remains unchanged.
What happens to a transparent background?
JPEG does not support transparency. This converter fills transparent areas with white.
Which settings can I change for PNG to JPG?
Width (pixels; 0 keeps original): Set the output width in pixels. Use 0 to keep the original width; proportions are retained. Default: 0. Quality: Choose a value from 1 to 100. Higher values keep more detail and may produce larger files. Default: 85.
Will the result be smaller or better quality?
A successful JPG conversion does not guarantee a smaller file or recovered detail. Container overhead, compression and the selected settings all affect output size. Check the saved result and keep the source if you might need a different export.
Why did my PNG file fail?
Read the message beside the file. A mismatched extension, corrupt data, unsupported feature or resource limit can prevent conversion. Check that the source opens normally, try the default settings and retry. The app will not offer a successful download for a failed job.
Where are files processed and how long are they kept?
Your browser sends selected files to the local server on this computer. No external conversion service is used. Temporary job copies expire after approximately 30 minutes; remove or clear deletes them sooner. Originals and downloads you saved are not overwritten.
