How it works

Three steps. Instant results.

Drop your PNG

Drag and drop PNG files onto the converter, or click to browse. No batch limit, convert as many files as you need.

Output format: JPEG

The format is set to JPEG automatically. Adjust the quality slider: quality 80 is the optimal starting point for most images.

Save your JPEG

Your converted JPEG saves directly to your device. Close the tab and browser memory clears completely. Nothing is stored or logged.

Why convert

PNG to JPEG: the right use cases.

PNG uses lossless compression, every pixel is stored exactly, but at the cost of large file sizes. For photographs and complex images without transparency, JPEG delivers the same visual result at a fraction of the size.

Photography and portraits

Photos saved as PNG are unnecessarily large. Converting to JPEG reduces size dramatically, typically 60-80%, with no perceptible quality loss at typical screen sizes.

Website hero images

Large banner images saved as PNG slow page load times. Converting to JPEG at quality 80-85 gives fast-loading images with excellent visual quality for web delivery.

E-commerce product photos

Product photography without transparent backgrounds is best served as JPEG on Shopify, WooCommerce, and Amazon, where PNG files are unnecessarily large.

Email marketing images

Embedded images in email newsletters need to be small. PNG photos in emails slow down rendering. Converting to JPEG keeps campaigns lightweight and fast.

Social media uploads

Instagram, Facebook, and X recompress images on upload. A pre-converted JPEG gives you control over the quality and avoids double-compression artefacts from platform processing.

Reducing cloud storage costs

Archiving large photo libraries as PNG consumes far more storage than necessary. Converting to JPEG at quality 85 can cut your storage footprint by 50-70% with near-identical visual output.

Lossy vs lossless: why JPEG wins for photos.

PNG uses lossless compression, meaning every pixel is stored exactly as it is. For photographs, this is unnecessary overhead. A photo encoded as JPEG at quality 80 is typically 60-80% smaller than the same photo saved as PNG, with no visible difference on any screen or printed at standard sizes.

The conversion runs entirely in your browser via the Canvas API. Your PNG is decoded to raw pixels, then re-encoded as JPEG at your chosen quality. Nothing leaves your device at any point.

Common questions

Questions answered.

Why convert PNG to JPEG?
JPEGs are significantly smaller than PNGs for photographs and complex images because they use lossy compression. If your image has no transparency and is a photo or detailed graphic, JPEG will give you a much smaller file with minimal visible quality loss.
How much smaller is JPEG than PNG?
For photos, JPEG is typically 60-80% smaller than PNG at quality 80. A 1 MB PNG photo often converts to a 150-300 KB JPEG with no visible difference on screen. The exact savings depend on the image content: photos compress more than flat graphics.
Will I lose transparency when converting PNG to JPEG?
Yes. JPEG does not support transparent pixels. Any transparent areas in your PNG will be filled with white in the JPEG output. If you need to preserve transparency, keep the PNG format or export to WebP instead.
What quality setting should I use?
For web use, 75-85 is the sweet spot: noticeably smaller files with near-identical visual quality. For print or archival purposes, use 90 or above. Quality 80 is a reliable default for most conversions.
Can I convert PNG screenshots to JPEG?
Yes, but screenshots with text and sharp edges can look slightly blurry in JPEG due to compression artefacts on hard edges. For screenshots, use quality 85-90 to preserve text sharpness. If pixel-perfect quality is critical, stay with PNG.
Will converting PNG to JPEG change the image dimensions?
No. The conversion only changes the file format and compression. The pixel dimensions remain exactly identical to the original PNG.
Is my image uploaded to a server?
No. All conversion happens entirely inside your browser using the Canvas API. Your files never leave your device.
Can I convert multiple PNG files at once?
Yes. Drop as many files as you need, there are no batch limits.
