Make photos small enough to email, attach to a form or put on a website. The compression runs in this tab, so your pictures never leave your device.
Add JPG, PNG or WebP images and select Keep format, JPG, PNG or WebP output.
Check the maximum width: its default is 1920 pixels. Choose Keep original size if dimensions must stay unchanged.
Adjust quality for JPG or WebP and compare the reported sizes after processing. PNG ignores this quality setting.
Save each result and inspect text and fine detail. Use Compress to a size for a specific KB target.
Dimensions and bytes are different requirements. Reducing width removes pixels, while lower JPG or WebP quality changes how remaining pixels are encoded. PNG does not shrink through a JPEG-style quality slider.
There is no guaranteed saving or exact size target here. A conversion can make a file larger. Batch processing applies the same settings to each image, and large decoded pictures can exceed available phone memory. Keep originals and compare actual results.
Choose Keep original size instead of the default maximum width. JPG or WebP quality changes can reduce bytes but also affect visual detail.
Use the dedicated HEIC to JPG tool if this browser cannot decode a HEIC here.
No. Processing happens on this device and creates separate downloads. Keep originals until you have checked the saved files.
The image is decoded, shrunk if you ask for a smaller maximum width, and encoded again. Most of the saving comes from the width. A phone photo is often over 4000 pixels wide, and 1920 is more than enough for a screen, so lowering the width makes a far bigger difference than lowering the quality. Images are only ever made smaller, never enlarged.
Quality runs from 30 to 95 percent and defaults to 75. Because the picture is redrawn, details such as camera information and location are not carried into the compressed copy.
By default each image keeps its own format, with anything unusual saved as JPG. WebP gives the smallest files at the same look. JPG is the most compatible and is what most upload forms want. PNG is lossless, which means the quality setting is ignored and a photo may not shrink at all, or may even grow.
JPG cannot hold transparency, so transparent areas turn white. Keep PNG or WebP if the background needs to stay clear. Each file is shown with its before and after size, so you can see exactly what you saved.
