Compress images online for free
To compress an image, save it again at a lower quality or make it smaller in pixels. Drop your photos in the box below and each one comes back as a smaller JPG, PNG or WebP file, free and without leaving your browser. A photo that cannot get smaller comes back unchanged.

Quick answer
How do I make an image file smaller?
Lower the quality of a JPG or WebP, reduce its width and height, or save a photo as JPG or WebP instead of PNG. JPG and WebP drop detail that is hard to see in a photo; PNG is lossless, so it keeps every pixel and stays larger. The quality setting changes JPG and WebP files only.
How each format compresses
| Format | Compression | Transparency | Quality setting | Best for |
|---|---|---|---|---|
| JPG | Lossy: drops some detail for a much smaller file | No (JPEG has no alpha channel) | Yes: a lower quality makes a smaller file | Product photos and marketplace uploads |
| PNG | Lossless: keeps every pixel exactly | Yes | None: PNG is lossless | Logos, screenshots, text and cut-outs on a transparent background |
| WebP | Lossy or lossless | Yes | Yes: a lower quality makes a smaller file | Photos and graphics on your own shop's pages, as smaller files |

How it works
Add your photos
Drop up to 20 photos on the box or choose them from your device. They open in your browser; nothing is uploaded.
Set quality, size and format
Quality starts at 80 of 100. Cap the longest side at 2000, 1600 or 1200 px if a photo is larger, and pick JPG or WebP for a smaller file.
Download
Each row shows the size before and after and how much was saved. Download one file, or all of them with Compress & download.
Questions
Yes. It costs no credits and needs no account.
No. The compressor opens, compresses and saves your photos in your browser. Nothing is sent to a server.
No. If the new file is not smaller than yours, for example a PNG that is already well compressed, you get your original back unchanged, and its row says so.
Start at 80, the setting the tool opens with, and compare the sizes. A lower number makes a smaller file and loses more detail, which shows first on text and sharp edges. The setting changes JPG and WebP files only.
No. A compressed file carries no EXIF or GPS data, so the camera, time and place are not passed on. The photo stays upright: its orientation is applied to the pixels first. A photo that could not get smaller comes back unchanged, data and all.
Safari cannot save WebP files from a web page; it saves PNG instead. So the compressor locks WebP there and says why. Chrome, Edge and Firefox save WebP.
