Kostenloser Online-Konverter PNG zu JPG

Convert PNG images to smaller JPEG files instantly with our free PNG to JPG converter on XConverters. Upload a PNG, adjust quality from 50 to 100 (default 90), and download a compressed JPEG — all lokal in Ihrem Browser verarbeitet with transformImage. Kein Konto, kein Upload, völlig kostenlos.

Was dieses Tool macht

PNG is ideal for graphics with transparency and sharp edges, but PNG files are often much larger than JPEG equivalents. When you do not need an alpha channel — for example on product photos, blog images, or social media assets — converting to JPG can dramatically reduce file size and improve page load times without visible quality loss at sensible settings.

Our converter accepts PNG uploads only and outputs standard JPEG files. Processing uses the transformImage engine entirely inside your browser, so your photos never travel to a remote server. That makes XConverters suitable for client work, personal albums, and any workflow where image privacy matters.

The Qualitätsschieberegler lets you balance compression against visual fidelity. At the default of 90, most photographs look excellent while saving substantial disk space and bandwidth. Lower values produce smaller files for thumbnails and previews; higher values preserve fine detail for print-adjacent use cases.

Unterstützte Formate und Anwendungsfälle

Common reasons to convert PNG to JPG on XConverters:

• Website performance: Replace large PNG hero images with lighter JPEGs to improve Core Web Vitals and reduce hosting costs.
• Email and messaging: Send photo attachments that meet size limits without visibly degrading quality at quality 85–90.
• E-commerce listings: Standardize product photos as JPEG for marketplaces that prefer smaller uploads.
• Blog and CMS publishing: Hochladen faster to WordPress, Ghost, or headless CMS backends that accept JPG.
• Social media prep: Prepare images where transparency is not needed and file size caps apply.
• Archive cleanup: Batch-convert legacy PNG screenshots to JPG when alpha channels are unused.

Note: JPEG does not support transparency. If your PNG uses alpha, convert only after flattening onto a background or use a tool that preserves transparency in another format.

Tipps für beste Ergebnisse

• Start at quality 90 and lower only if you need a smaller file — it is the best default for most PNG photos.
• Avoid converting logos or UI assets that rely on crisp transparency; keep those as PNG or SVG.
• Compare file size before and after — savings of 50–80% are common for photographic PNGs.
• Use higher quality (95–100) when the JPG will be edited again or printed.
• If colors look wrong, ensure your PNG was sRGB; wide-gamut sources may shift slightly in JPEG.
