80 KB is a comfortable size for one photograph: enough for an upload form, a listing, a document scan or an image on a web page, at a size people view on screen. A phone photo needs to come down in pixel size a little to fit, and this page finds the largest it can keep at good quality.
What fits in 80 KB
A photograph up to about 629 × 419 pixels at high quality, or 873 × 582 at the lower quality most forms accept. That is measured on a detailed outdoor photo; a portrait against a plain wall fits larger.
A signature on white paper up to about 2111 × 792 pixels, more than any form asks for.
Is 80 KB enough?
A photo on an application form, shown at about 200 × 230 pixels: yes, at high quality.
A profile picture at 400 × 400: yes, at high quality.
A passport photo printed at 35 × 45 mm (413 × 531 pixels at 300 dpi): yes, at high quality.
A photo shown across a phone screen, about 1080 × 720: not at full size; at 80 KB it comes out smaller.
A photo filling a Full HD screen, 1920 × 1080: not at full size; at 80 KB it comes out smaller.
80 KB against the sizes either side
The same photograph reaches about 629 pixels wide at 80 KB, against about 582 pixels wide at 70 KB and about 720 pixels wide at 100 KB. If the form allows more than 80 KB, the next size up is a visibly sharper picture.
For a web page, consider WEBP
If the image is going on your own site, WEBP looks the same at roughly a quarter less, and every current browser shows it. Compress Image writes WEBP directly. Forms, though, nearly always want JPG, which is what this page produces.
If the website still says the file is too big
This page counts 80 KB as 81,920 bytes. Some sites count it as 80,000, which is a little less. If yours is strict, aim for the next size down.
Questions
How do I compress an image to 80KB?
Add it to this page and press the button. The JPG quality is lowered step by step and, if that is not enough, the pixel size, and the best version under 80 KB is kept. For a typical photo that ends up about 629 pixels wide.
How many pixels is a 80KB photo?
About 629 × 419 at high quality, or 873 × 582 at a lower one, for a detailed photograph. A simpler picture fits more pixels in the same size.
Can I compress a PNG or an iPhone photo to 80KB?
Yes. PNG, HEIC and WEBP are all read and saved as JPG. To fit 80 KB, a detailed photo comes down to about 873 pixels wide at the quality forms accept; a scanned signature keeps up to 2111.
Is my photo uploaded?
No. It is compressed in your browser, on your own device.
