When a PNG is better saved as JPG
Screenshots, photos from some programs and exports from design tools are often saved as PNG. For a photo that is a waste: as JPG it is 5 to 10 times smaller and looks the same.
Good to know
- Transparency: JPG has no transparent background. Transparent areas become white.
- Text and logos: sharp edges and flat areas look best as PNG. Compress those with Compress PNG instead.
- Quality: 90 is virtually identical to the original, 80 is plenty for websites and email.
Keep transparency?
Choose WEBP under Save as. WEBP supports transparency, is as small as JPG, and every modern browser shows it.
How it works
Three steps to resize, optimize or convert any number of images.
Upload images
Drop, paste or pick any number of JPG, PNG, WEBP, GIF, TIFF, AVIF, HEIC or SVG files.
Choose the settings
Pick a size, format and quality. Save them as a profile so they are ready next time.
Download
Every image is processed on the server, in memory. Download them one by one or all at once as a ZIP.
Features
Powered by libvips, the same engine large photo sites use. Nothing is stored, nothing goes to third parties. The demos below are live: try them.
Resize
Set a width, a height, a percentage or a box to fit in. Give one side and the other follows the aspect ratio. "Exact" forces a size and crops the rest with smart cropping.
Need the same size for a whole batch? Drop them all at once; the settings apply to every image.
Try it: change the width on the right.
Optimize
Choose a quality from 1 to 100, or set a maximum file size in KB and let the tool find the highest quality that fits. Metadata such as GPS location is stripped by default.
Lossless mode for logos and screenshots, mozjpeg for JPG, and fine control over chroma subsampling, effort and sharpening under Advanced.
Try it: drag the line and move the quality slider.
Convert
Turn anything into JPG, PNG, WEBP or AVIF, or keep the original format. The format you pick stays selected for every image you add, no surprises.
WEBP is typically 25–35% smaller than JPG at the same quality and works everywhere; AVIF is smaller still for modern sites.
Try it: pick a format and watch the file size.
Crop
Open any image from the list and drag a crop box over it, free or locked to a ratio. Social presets for Instagram, Facebook, X, LinkedIn and YouTube set both the crop and the exact output size.
The crop only applies to that one image; everything else keeps following your global settings.
Try it: drag the box or its corners, or pick a preset.
Frequently asked questions
What happens to a transparent background?
It becomes white, because JPG does not support transparency. To keep it, choose WEBP or leave it a PNG.
Is JPG always smaller than PNG?
For photos almost always, often 5 to 10 times. For logos and screenshots with few colours a compressed PNG can be smaller and sharper.
Can I change the dimensions too?
Yes, choose Fit in with 1920 pixels under Resize, for example.
How many PNGs can I convert at once?
Up to 50 at a time, each up to 25 MB. Download them one by one or as a ZIP.
