Compress Image to 150 KB
Compress a detailed photo to 150 KB, enough to keep a portrait or product shot sharp while leaving a wide margin under 200 KB caps.

Never shrink below this width when downscaling. 0 means no minimum.
Optionally set the dimensions before compressing. Forms that specify pixels as well as KB need both.
Pixels for the side you chose above.
The search for the target size will not go below this quality; it downscales instead.
4:2:0 halves color resolution and saves a lot on photos; 4:4:4 keeps sharp edges on text, logos and screenshots.
Lossy PNG quantises colors (like TinyPNG) and is far smaller; lossless keeps every pixel.

When is 150 KB the right target?
When the limit you face is 200 KB or higher but you want a clear margin, or when the image is going on your own page or into an email and should load quickly without looking soft.

A margin under 200 KB caps
We know of no official form that names 150 KB itself. It is popular because it sits safely below a common round cap. UPSC's 2026 CAPF examination notice allows a photograph of 20 to 200 KB, and NTA's NEET (UG) 2020 notice set the passport-size photograph at 10 to 200 KB. A 150 KB file is inside both windows with room to spare.
If you would rather use the full allowance, the 200 KB preset goes right up to the cap. The extra 50 KB is rarely visible in a passport-style photo, though, and the smaller file uploads faster on a weak mobile connection, which matters when a portal is busy near a deadline.
Read the floor as well as the cap. A notice that says "20 to 200 KB" rejects a file of 15 KB just as firmly as one of 210 KB. At 150 KB the floor is never a concern, which makes this target a calm choice when you are not sure how strictly a portal checks, or when the notice for your exam is hard to find.
Three common uses
Beyond forms, 150 KB is a comfortable size for pictures that people look at on a screen. The settings that work best differ by where the image goes, so the tabs below give a starting point for each case. All of them start from the same target and only change the format and the width.
Width matters more than format. A photo stored at 4,000 pixels and shown at 1,000 spends most of its 150 KB on detail nobody sees, so the tool has to lower quality to fit. Resized to the display width first, the same photo keeps a high quality and looks sharper on screen, even though the file size is identical.
Keep the photo as JPG, which every portal accepts, and set the pixel size the notice asks for.
- Output format: JPG
- Resize first: the width in the notice
- Strip metadata: on
Use WebP for the best detail per kilobyte and match the width to the space on your page.
- Output format: WebP
- Resize first: your display width
- Keep color profile: on
Keep JPG so every mail app shows the picture inline, and choose a width that fills a phone screen.
- Output format: JPG
- Resize first: set longest side
- Strip metadata: on to remove location
What the tool does to reach 150 KB
Compression starts at the top: the tool searches for the highest quality at which the file fits in 150 KB. With this much room, most photos of a sensible size stop there, so the pixels stay exactly as they were. Only a very large original, such as an uncropped photo straight from a recent phone, also needs its dimensions reduced, and that happens in small steps after quality has reached the lowest value you allow.
Each image in a batch is handled on its own, so a small file is not pushed down to match a big one. Files already below 150 KB are left alone apart from metadata. The limits above are those of this tool: each upload can be up to 95 MB and a batch up to 20 files. The Gmail figure is there for comparison, since a whole set of 150 KB photos fits in one email with plenty of room.
For fine control over quality levels, percentage mode and PNG settings, open the main Compress Image tool. If a form sets a pixel size in centimeters, convert it first with the Resize Image tool.
Compress an image to 150 KB in three steps
Add your photos
Drop the images on the box above or press Choose Files. JPG, PNG, HEIC, WebP and AVIF are all accepted.
Use the 150 KB target
The size is set. Choose an Output format if the destination needs one, and a width under Resize first if you know how large it will be shown.
Compress and save
Press Compress. Download each file, or all of them at once, when the new sizes appear.
Compress to 150 KB questions
My form allows up to 200 KB. Is 150 KB too small?
No. Forms with a 200 KB cap almost always have a low floor, often 10 or 20 KB, so 150 KB is well inside the window. It also leaves room in case the portal measures size slightly differently from your computer.
How large can a photo be at 150 KB without looking compressed?
It depends on the content. A portrait with a plain background keeps a high quality at a larger pixel size than a busy street scene, because flat areas need fewer bytes. Let the tool decide; it keeps the full size whenever the quality it needs still fits.
Is 150 KB a good size for a CV or profile photo?
Yes for most job sites and profile pages, which display the picture small. Crop to head and shoulders, keep JPG, and the face stays sharp at 150 KB. If the site lists its own limit, use that number instead.
Can I compress a 150 KB photo for a website product page?
Yes, and WebP is a good output format there, since every current browser opens it and it holds more detail per kilobyte than JPG. Set the width to the size your page displays so no bytes are wasted on pixels nobody sees.
Will the image keep its EXIF date after compressing?
Not by default. Strip metadata removes the date, location and camera details. Switch it off under Metadata & color profile if your photo library sorts by the date stored in the file.
Does a 150 KB PNG make sense?
For a screenshot, chart or drawing, yes. For a photo, PNG is the wrong container at this size: it stores every pixel without loss and has to discard colors to fit. Convert photos to JPG or WebP instead.
