Compress images: JPG, PNG and WEBP
Make picture files smaller: at a quality you choose, or under a size such as 100 KB.
or drop them here. It stays on your device: nothing is uploaded.
How to compress an image
- 1Choose quality or sizeQuality sets how much detail is kept. Target size makes each file fit under a number of KB, such as 100 KB for a form.
- 2Add your picturesUp to 30 at once. Each row shows the size before and after, and the files are done again when you change a setting.
- 3DownloadOne at a time, or all in a ZIP.
How much smaller?
A phone photo of 3 to 5 MB usually comes down to 400 to 900 KB at 75% quality with no difference you can see on a screen, and to under 300 KB if the longest side is also set to 1920 pixels. WEBP saves about another quarter. Screenshots and graphics saved as PNG shrink most when their colors are reduced.
Keep the original for printing
Compress copies for email, websites and upload limits, never the file you send to a printer. For print, what matters is pixels per inch; the print size calculator tells you whether a picture is large enough.
Nothing is uploaded
The compressor works in your browser, on your own device. Camera data and GPS position are dropped from every file.

Questions people ask
How do I compress an image to 100 KB?
Choose Target size and 100 KB, or type any size. Each picture is saved as a JPG at the highest quality that fits under it. If even a low quality does not fit, it is also made smaller in pixels, step by step, until it does.
Does compressing an image reduce its quality?
A JPG or WEBP leaves out detail the eye barely sees, more at a lower quality. Between 70% and 80% the difference is hard to spot in a photo, and the file is often a third of the size. A PNG is made smaller by using fewer colors, which suits graphics and screenshots more than photos.
How do I compress a PNG?
Keep PNG and lower the quality: below 90% the picture is kept to 256 colors or fewer, which often halves the file and keeps transparency. For photos, saving as JPG or WEBP makes a far smaller file than any PNG.
Should I choose JPG or WEBP?
A WEBP is usually 25% to 35% smaller than a JPG that looks the same, and it can be transparent. Websites and browsers open it, but some apps, printers and upload forms do not, so choose JPG when you are not sure.
Should I compress a file I want printed?
No. Compression is for email, websites and upload limits. A printer or print-on-demand supplier wants the full-quality file; every bit of detail taken out can show up in the print.
Are my images uploaded?
No. The compressor runs in your browser: pictures are opened and saved on your own device and never sent to SlapMake or anyone else. Camera data and GPS position are dropped, which makes the files a little smaller too.
