À propos de l'outil PNG en JPG
This converter turns a PNG image into a JPG, usually shrinking the file dramatically - a photo saved as PNG is often 5–10× larger than the same photo as a high-quality JPG. Convert when a form or portal rejects PNG or enforces a size limit, when email attachments are too heavy, or when you need faster-loading images and WebP is not an option. One thing to know before converting: JPG does not support transparency. If your PNG has a transparent background (common for logos), the transparent areas will be filled with a solid background in the JPG. For logos and graphics with sharp text, PNG or WebP usually remains the better format; for photos, JPG is exactly right.

How to convert PNG to JPG and keep the file small
Upload your PNG, press convert and download the JPG. A photo saved as PNG is often 5 to 10 times larger than the same photo as JPG, so this is the quickest way to get under an upload size limit.
Need a specific size such as 200 KB or 100 KB? Convert to JPG first, then run the result through the Image Compressor and lower the quality until it is under your limit.
PNG or JPG: which is better?
Use JPG for photos, email attachments and forms with size limits. Use PNG for logos, screenshots with small text, and anything that needs a transparent background.
Questions fréquentes
What happens to a transparent background?
JPG cannot store transparency, so transparent areas of the PNG are filled with a solid background color in the output. If you need to keep transparency, stay with PNG or convert to WebP instead.
How much smaller will my file get?
For photographic images, typically 70–90% smaller. For screenshots and graphics the saving is smaller, and fine text may show slight JPG artifacts.
Does converting to JPG lose quality?
JPG is a lossy format, so a small amount of detail is discarded - at the quality level used here it is generally invisible for photos. Avoid converting images you plan to edit repeatedly.
When should I NOT convert PNG to JPG?
Logos, icons, screenshots with small text, and images needing transparency. JPG artifacts show most on sharp edges and flat colors - exactly what those images contain.
Is this the same as compressing the image?
Related but different: this changes the format. If you want to keep PNG format but reduce size, use the Image Compressor tool instead.
How do I convert PNG to JPG under 200 KB?
Convertir the PNG to JPG here, then use the Image Compressor and reduce the quality until the file is under 200 KB. Photos usually reach that size easily.
the converter est-il gratuit ?
Yes - free, no account, no watermark, and uploads are cleaned from temporary storage automatically.
