Image Compressor
Shrink JPG, PNG and WebP images in your browser, or hit an exact file size like 200 KB. 100% free, no signup. Everything runs in your browser.
This free image compressor shrinks JPG, PNG and WebP files right inside your browser, and your photo never leaves your device. Most compressors work by uploading your file to a server, processing it there and sending it back. Ours does not need to, because your browser can already decode and re-encode images on its own. Drop in as many images as you like, pick a preset such as Form or portal upload, and watch the sizes fall as you adjust. If a website or an application demands a specific limit, set a target like 200 KB and the quality is worked out for you until the file fits. You can compare the result against the original before you download, so you are never guessing whether the saving cost you anything visible.
How to use
- Drop your images onto the box, or tap Choose files. You can add several at once, and you can paste an image straight from your clipboard.
- Pick a preset. Form or portal upload targets 200 KB for exam, visa and job sites. Website or blog gives WebP at 1600 pixels wide. Email attachment keeps you under the 1 MB most mail systems allow.
- If you need an exact size, set a target. Type a number or tap one of the quick sizes, and the quality is worked out for you until the file fits.
- Watch the numbers move as you adjust anything. There is no Compress button because it compresses as you go.
- Check the result with the Before and After buttons above the preview. Zoom to 100 percent first, because at fit to screen no compression is visible on any photo. You can also press and hold the image to peek at the original.
- Download a single image with the arrow on its row, or use Download all to get everything as one ZIP file.
Why use our image compressor?
The reason to use this one is simple: your image never goes anywhere. Product photos before a launch, scans of documents, client artwork under contract, personal pictures you would rather not hand to an unknown server. All of it stays on your machine. That is not a promise we are asking you to trust, it is how the tool is built. Load the page, turn off your wifi, and it still works.
It is also faster in practice, because there is no upload and no download from a server. A ten megabyte photo compresses as quickly as a small one, and there are no daily limits, no file size caps and no queue. You get real control too. Quality, output format and maximum width are all in your hands, and you see the exact saving before you commit. When your images are ready, the word counter helps you keep the surrounding copy tight, and the QR code generator turns the finished page into something printable.
Who is this tool for?
Website owners and bloggers get the most obvious win. Images are usually the heaviest thing on a page, and heavy pages lose visitors and rank worse. Cutting a page of photos from four megabytes to four hundred kilobytes often takes seconds per image and makes a site feel completely different on a phone. Online sellers on Etsy, eBay, Shopify or Facebook Marketplace hit upload size limits constantly, and a quick compress solves it without buying software.
Students and office workers use it when a form refuses a photo that is too large, or when an email attachment will not send. Job applicants shrink a scanned certificate to fit an upload limit. Designers and photographers make lightweight previews for clients while keeping the originals untouched. Anyone posting to a forum, a listing site or a school portal that caps uploads at two megabytes has needed this tool at some point, usually in a hurry.
Frequently asked questions
No. The file is read into the page and processed by your own browser using the canvas API. It is never transmitted. You can load this page, disconnect from the internet, and the compressor still works normally.
Photos usually drop by 60 to 90 percent at 80 percent quality, which is a large saving for no visible change. Screenshots and graphics with flat color vary more. The tool shows the exact figure before you download, so you can try a different setting if you are not happy.
Yes. Set a target size, either by typing a number or tapping one of the quick sizes, and the tool tries different quality levels until the file lands under your limit. It takes a few attempts behind the scenes and stops as soon as it is within about four percent of your target, so you get the best quality that still fits. If the limit is very tight for the size of the picture, it will also reduce the width, and it tells you when it cannot go any lower. This is the setting most people want when a government form, an exam portal or a job site refuses their photo.
Start at 80. For photos on a website you can often go to 70 without anyone noticing. Below about 50 you start to see blocky patches in skies and smooth gradients. For anything being printed, stay at 90 or above.
WebP files are usually 25 to 35 percent smaller than JPG at the same quality and every modern browser supports them, so choose WebP for websites. Choose JPG when you need something that opens everywhere, including older software and some print shops.
PNG is lossless, so re-encoding it does not always help, and a photo saved as PNG is always huge. If your image is a photo, switch the output format to JPG or WebP and the file will shrink dramatically.
Yes. Because the image is redrawn onto a canvas, EXIF data such as camera model, date and GPS location is not carried over. Many people count that as a privacy bonus, but keep your original if you need that information.
No limits at all. Since nothing is uploaded there is nothing for us to meter. Very large images depend on your device's memory, but anything from a normal camera or phone is fine.
