Two Ways to Reduce Image Size
There are two different things people mean when they say "reduce image size." The first is reducing file size (how many KB or MB the file takes up) while keeping the same pixel dimensions. The second is reducing pixel dimensions (making the image smaller in width and height), which also reduces file size as a side effect. This tool does the first. If you want the second, use the resize tool.
Reduce File Size vs Reduce Dimensions
| Method | What Changes | When to Use |
|---|---|---|
| Compression (this tool) | File size only, pixels stay the same | Email, web upload, government forms with KB limits |
| Resize | Pixel dimensions and file size both reduce | When the portal specifies exact pixel dimensions (e.g. 200x230 px) |
| Both together | Optimal file size with exact dimensions | Government exam photos, profile photos with size and KB limits |
How to Reduce Image Size Step by Step
- Drop your image into the tool above or click to select it from your device.
- Choose your output format. For photos, JPEG gives the best compression. For graphics with transparency, keep PNG.
- Adjust the quality slider. Start at 82 and preview the result. Only go lower if the file is still too large.
- If you have a specific KB target, switch to target-size mode and enter the limit.
- Click download to save your compressed image.
Frequently Asked Questions
How do I reduce image size for government exam upload?
For government exams like SSC, IBPS, or RRB, you usually need to do two things: resize to specific pixel dimensions (like 200x230 px) and compress to a specific KB limit (like 50KB). Use the resize tool first, then use this compression tool with target-size mode set to the required KB limit.
Can I reduce image size without losing quality?
Up to a point, yes. JPEG compression at quality 80 to 90 is largely invisible at screen viewing distances. Once you go below quality 70, you'll start to see compression artifacts. The right balance depends on your use case.
Why is my PNG not reducing in size much?
PNG uses lossless compression, which means there's less room to compress it further. If your image is a photograph (not a graphic), convert it to JPEG format in this tool. JPEG compression will reduce it by 60 to 80 percent more than PNG compression can.
What is the maximum image size I can reduce here?
There's no set limit, but very large images (above 20MB) may take a few seconds to process on slower devices since everything runs in your browser. For most use cases, the tool handles images up to 50MB without issues.
How do I reduce image size on my phone?
Open this page on your phone's browser, tap "Select Image" and choose from your camera roll. The tool works the same on mobile as on desktop, and all processing happens on your phone locally.
