Target size (KB)
A built-in 5% safety margin is applied (e.g. a 50KB target compresses to ≈47KB), so uploads are never rejected for being just over the limit.
Quality 5–100：
Could not reach target size
Lower the quality further or resize the image, then try again.
Transparent image — kept as PNG
Compress PNG to 100KB while keeping transparency
Government job portals, school application systems and email attachments often impose a hard 100KB limit on images. Our tool binary-searches the optimal quality level to shrink JPG, PNG, WebP or HEIC photos to under 100KB while keeping as much detail as possible — fully processed in your browser, no upload, no sign-up, unlimited.
Common scenarios with a 100KB limit
| Scenario | Typical limit | Required format |
|---|---|---|
| Government job portals (SSC, UPSC, etc.) | Photo 20-100KB | JPG |
| School & exam applications | Photo 100KB | JPG/PNG |
| Email attachments | 100KB – 2MB | Any |
| E-commerce product images | 100–500KB | JPG/WebP |

Private, processed locally
Files are processed only in your browser and never uploaded, so even sensitive photos stay safe.
Batch processing + ZIP
Compress many images at once and download them all as a single ZIP.

Frequently asked questions
Does PNG compression keep transparency?
Yes. Choose PNG or WebP output to keep the alpha channel intact. Transparent areas are compressed separately, and the tool only warns if a fully transparent image can't reach the 100KB target without visible artifacts.
Why is my PNG so large to begin with?
PNG is lossless, so it stores every pixel exactly — a 12MP photo as PNG can exceed 10MB. That is normal; this tool's job is to squeeze it below 100KB while keeping the parts that matter (edges, text, transparency) clean.
Will text or logos stay sharp at 100KB?
Yes. The tool detects hard edges and text-heavy content, and spends the size budget on them. Screenshots, diagrams and logos remain readable — unlike naive JPEG recompression.
Which input formats are supported?
JPG, PNG, WebP, AVIF, BMP, GIF and HEIC all work. Output can be PNG (transparency), WebP (small + transparency) or JPG (smallest, no transparency).
Is it safe for confidential graphics?
Yes. Processing is 100% local — your PNG never leaves the browser, so it is safe for logos, screenshots and internal documents.
