For forms, listings and uploads that stop at 150 KB." url: "https://imagecompressor.si/compress-image-to-150kb" lang: "en" --- # Compress an image to 150 KB Bring a photo, scan or screenshot down to 150 KB, with the quality set as high as the limit allows. ## How it works 1. **Add your images** Drag and drop, paste, or pick files. They upload over an encrypted connection. 2. **Pick a quality or a target size** Use the quality slider, or tell it exactly how many KB or MB you need. 3. **Download** Save each file, or grab them all at once as a ZIP. A limit of 150 KB sits between the tight sizes of exam forms and the roomy ones of e-mail. You meet it on property and classified listings, on some university and visa portals for a photograph or a scanned page, and on community sites that cap avatars and attachments. It is enough for a sharp photo at a sensible size, which is why the right settings matter more than raw squeezing. Add your picture and it is compressed to the largest file that still fits under 150 KB: the quality is searched for rather than guessed, so you lose no more detail than the limit forces. Turn on resizing in the same panel if the photo is huge; a smaller picture at 150 KB keeps more of its sharpness. The result is shown with its exact size in kilobytes, and a picture that cannot reach the limit is marked as such rather than handed over too big. You can download each file, or all of them in one ZIP. ## Getting the best picture at 150 KB A photo straight from a phone is often four or five thousand pixels wide, far more than any page shows. Shrinking it to about 1,600 pixels on its long side first leaves room for higher quality at 150 KB, and the picture looks better on screen than a full-size one squeezed hard. Screenshots and diagrams with flat colour often stay sharper as PNG or WebP; set the format in Advanced if the JPEG shows smudges around text. ## Scans and documents For a scanned page, crop the table or floor around the paper before compressing, so the bytes go into the text. A flat, evenly lit page compresses far better than one with shadows across it. ## Several files at once Add a batch of pictures and each one is brought under 150 KB separately. That suits a listing with a dozen photos, all with the same limit. Each file shows its own size, so you can see at once which is ready and which needs a smaller width. ## Your pictures They are compressed on our server and deleted from it once the result is ready. ## When 150 KB is not reached A picture full of fine detail, such as leaves, gravel or crowd scenes, may not fit at its current pixel size. Turn on resizing and give it a smaller width, or crop it to the part that matters; either frees enough bytes to reach the target. ## Checking the result Look at the picture at full size before uploading, especially faces and small text. If they are clean, the file is ready; if they show blocky patches, a smaller pixel size at the same 150 KB usually looks better than more compression. ## Frequently asked questions ### Will the file be exactly 150 KB? It will be at or just under 150 KB, as close as the format allows. ### Is 150 KB here 150,000 bytes? Yes, which is also under 150 KB on portals that count 1,024 bytes to a kilobyte. ### Can I keep PNG? Yes. Set the format in Advanced; the target still applies. ### Can I compress many images? Yes. Each is brought under 150 KB on its own. ### Is my photo stored? No. It is removed from our server once it has been compressed. ### Should I make the picture smaller in pixels too? For a big phone photo, yes: a slightly smaller picture looks sharper than a full-size one squeezed into the same 150 KB. ### What if I need 100 KB instead? Use the 100 KB page, or type your own number in the settings. ## Related tools - [Compress an image to 100 KB](https://imagecompressor.si/compress-image-to-100kb): A popular limit for web forms, applications and email attachments. - [Compress an image to 200 KB](https://imagecompressor.si/compress-image-to-200kb): A generous limit that keeps most photos looking close to the original. - [Convert JPG to a PDF under 200 KB](https://imagecompressor.si/jpg-to-pdf-under-200kb): Several pages in one PDF, under 200 KB altogether, with enough room left for the small print to stay legible.
