Compress Image to 150KB Online

For NEET, JEE Main, and UPSC — yes, 150KB sits safely under all three of their photograph ceilings. For SSC, IBPS, and ICAI, no — those portals cap photographs at 50KB, so use our 50KB tool for those specifically.

More of the original detail survives compression, particularly around hair, eyewear, and photo backgrounds. If your target portal allows up to 200KB or more, there's no reason to compress harder than necessary.

Many state recruitment boards accept certificate scans as JPG within a 100–200KB range, though a growing number now require PDF instead. Check your specific notification's document-upload section before scanning as an image.

Yes. 150KB is well within Google's guidance for fast-loading in-article images, especially when paired with modern formats like WebP, which our tool selects automatically when your browser supports it.

1KB equals 1,024 bytes in this tool (and in Windows/macOS), so a file listed as under 150KB is at most 153,600 bytes. If a portal's own size checker uses 1,000 bytes per KB instead, your file will still pass since it's comfortably under either definition.

For most photos, yes — at 150KB you can expect a result that looks close to indistinguishable from the original on a phone or laptop screen. The exact outcome still depends on how detailed and high-resolution your original photo is; a simple, well-lit photo compresses more cleanly than a busy, low-light one.

If your form specifies exact dimensions, match those first — commonly your original dimensions. Our tool not needed for typical photo or web-image dimensions while compressing, so starting with roughly the right dimensions gives the cleanest result.

Yes. Upload your PNG here, select JPG from the Output Format dropdown, and set your target to 150KB — the tool converts and compresses in the same step, which is handy for a social media image.

No, and we structurally can't — there's no upload step in this 150KB tool at all. Everything happens client-side via JavaScript and Canvas, so your file never leaves your device.

Yes, one at a time, which lets the tool fully optimize each file for exactly 150KB rather than applying one generic setting across a batch. You can reset and compress another image immediately after downloading.

Your iPhone is likely saving photos as HEIC, which isn't accepted here (we support JPG, PNG, WebP, AVIF, GIF, and BMP for the 150KB target). Switching to Settings → Camera → Formats → "Most Compatible" saves future photos as JPG, which will upload fine.
