Image to 150 KB and the size on the form
150 KB is enough for a clear face photo when 50 KB made the picture muddy.
The browser writes a JPG aimed at 150 KB. Nothing is uploaded.
If it is still too big
Only use 150 KB if the form allows it. A portal that says 50 KB will reject a perfect 150 KB file.
Pixel rules and kilobyte rules are different. Resize first when the portal asks for both.
Image to 150 KB without the extra promises
Image to 150 KB sits on this site because Image and 150KB are not interchangeable, even when they look similar in a file list. 150 KB is enough for a clear face photo when 50 KB made the picture muddy. Resize, crop, rotate, compress, or change a photo when the next form has rules. Use 150 KB only if the form allows it. It is the wrong target when the form says 50 KB or 20 KB.
The browser writes a JPG aimed at 150 KB. Nothing is uploaded.
Read this about Image before you upload
Image tools redraw the picture in your browser. They do not upload the file. These tools do not recover detail the camera never captured. Upscale and HD modes enlarge pixels. They are not AI reconstruction.
Keep the original photo.
Read this about 150KB before you send the download
The download has to be 150KB, because that is the format the next step named. Use 150 KB only if the form allows it. It is the wrong target when the form says 50 KB or 20 KB. Detail holds up better than the tighter caps.
The picture is not uploaded. Compression runs in the browser.
Keep, check, then delete
People lose time when they convert before they know which rule failed. Size, pixel dimensions, codec, font encoding, and layout are different rules. Image to 150 KB only addresses the Image to 150KB step. 150 KB is enough for a clear face photo when 50 KB made the picture muddy. The browser writes a JPG aimed at 150 KB. Nothing is uploaded. Only use 150 KB if the form allows it. A portal that says 50 KB will reject a perfect 150 KB file. The file stays in your browser and is not uploaded. The limit is 100 MB. Keep the original until the download has been opened in the program that will use it. Do the test with a short or simple file first when the real file is large. A one-page PDF, a single photo, or a one-minute clip will show you whether the output is the kind of file you needed. After that test looks right, run the real file once. Keep both the Image original and the 150KB download until the receiving person or the upload form accepts it. Photos fail uploads for three separate reasons: the format name, the pixel size, and the kilobyte size. Image to 150 KB only does the Image to 150KB step. If the form also prints a pixel size or a 20 KB or 50 KB cap, do that step with the matching tool, starting from the original each time. A second lossy save will not recover detail.
Here is the decision for Image to 150 KB. You start with Image and you stop when a real program accepts 150KB. The original pixels are what you have to work with. The edit is local. A portal does not round up. 160 KB fails a 150 KB rule, and 150 KB fails a 50 KB rule. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.
Only use 150 KB if the form allows it. A portal that says 50 KB will reject a perfect 150 KB file.
A related step, if you still need one, is Image Compressor.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
