Hits an exact KB limit
Fast, consistent results
These are the limits people hit most often. If your form says something else, type the exact number in the custom field.
| Target size | Typical use |
|---|---|
| 20 KB | Very tight limits: some national ID and visa portals. |
| 50 KB | Most passport, visa and exam application forms. |
| 100 KB | Job portals, university applications, email attachments. |
| 200 KB | Common blog and forum uploads, marketplace listings. |
| 500 KB | Websites, Shopify and WordPress featured images. |
| 1 MB | High-quality web and social media uploads. |
Pick the recipe that matches what you are doing. The tool does the rest.
Portals often reject anything over 50KB or 100KB. Use target size mode, pick 50KB or 100KB, and the compressor finds the sharpest quality that fits.
Big photos slow your site down. Compress to WebP at 75 to 85% quality and you will often cut file size by 60% with no visible change.
Most inboxes cap attachments at 20 to 25MB total. Compressing a batch of photos to JPG at 80% quality usually gets you under the limit in one pass.
Sites like Facebook Marketplace, eBay and Gumroad limit each photo. Compress to 200KB or 500KB so listings upload fast and still look sharp.
Instagram, X and Facebook re-encode every upload. Sending a moderately compressed JPG at 80% quality often looks better than a huge original after their own compression.
Scans from a phone camera are often 5 to 15MB each. Compressing to 100KB or 200KB keeps text readable and makes PDFs and forms a fraction of the size.
Same photo, three formats, three different outcomes. Here is the short version.
The most compatible format. Works in every app, browser and printer.
About 25 to 35% smaller than JPG at the same quality. Supported by all modern browsers.
Lossless, so nothing is thrown away. Best when you plan to edit further.
A few habits keep your photos looking sharp after they shrink.
A full-resolution original gives the compressor more to work with. Compressing an already-compressed copy twice will look worse than compressing the original once.
WebP files are usually 25 to 35% smaller than JPG at the same visible quality. All modern browsers, Android and most desktop tools open them.
JPG cannot hold transparent pixels. If your photo has a logo cutout or rounded corners, save as PNG or WebP so the background does not turn black or white.
Below about 60% quality, skin tones and fine text start to look blocky. Aim for the smallest file that still looks good to you, not the smallest file possible.
Before you download, drag across the comparison view. If you can spot the difference, raise the quality or increase the target size a little.
No. Every photo is opened, compressed and saved by your own browser. Your files never leave your device. There is no upload step and no server involved in the compression.
You tell us the size you need, for example 100 KB, and the compressor searches for the best quality that still fits under that size. This is perfect for forms that reject files above a limit, like passport or visa applications.
Quality mode compresses every photo at the same quality level and gives you small files quickly. Target size mode does a few extra passes to hit an exact KB limit while keeping the best quality it can. Target size is slower but more precise.
Compression always trades a little detail for a smaller file. At high quality settings most photos look identical to the original. You choose the balance, and you can compare before and after on screen before you download.
You can add JPG, JPEG, PNG, WebP, AVIF and most other image formats your browser can open. You can save the result as JPG, PNG or WebP.
JPG makes the smallest files and works everywhere. WebP is even smaller at the same quality and is supported by all modern browsers and apps. PNG is lossless and best when you need transparency or exact pixels, but the files are much bigger.
A few photos, especially those with a lot of fine grain or noise, cannot be squeezed under very small limits without looking bad. The compressor stops before destroying the photo and tells you the smallest size it could reach. Try saving as WebP, or choose a slightly larger target.
You can add up to 20 photos at once, up to 25 MB each. When they are done you can download them one by one or all together as a ZIP file.
Once the page has loaded, you can switch off your connection and keep compressing. Reloading the page offline will not work unless your browser has cached the files.
No. There is no limit, no daily cap and no sign-up. Use it as often as you like.
There is no upload step and no account. The compression is done by your browser using your own processor, and the finished files are saved straight to your downloads. Nothing is stored, nothing is logged, and the same page keeps working even if you go offline. Read the full explanation on our privacy section.
