About Compress Image to Target Size (e.g. 20KB, 30KB, 50KB)
The Image Compressor reduces the file size of JPG, PNG and WebP images by re-encoding them with smarter settings, stripping unused metadata and optionally resizing dimensions. A 6 MB phone photo typically shrinks to a few hundred KB with no visible quality loss.
The quality slider controls the trade-off between storage and detail, while optional width reduction can deliver larger savings than compression alone for oversized camera images. Before-and-after sizes make the effect measurable instead of forcing you to guess whether a new setting is worthwhile.
Compression runs in your browser — personal photos and ID scans never leave your device. Several images can be processed in one batch and downloaded individually or together, while the originals remain untouched for archival or print use.
How Compress Image to Target Size (e.g. 20KB, 30KB, 50KB) works in practice
- 1Drag your images onto the upload area (JPG, PNG or WebP).
- 2Adjust the quality slider — 70–85% is a good default for photos.
- 3Optionally set a maximum width to resize huge images at the same time.
- 4Click "Compress" and compare the new size against the original.
- 5Download the compressed files individually or as a ZIP.
Jobs this tool is built for
- Shrink phone photographs below an online form's per-file upload limit.
- Optimise product photos and article images to improve website loading on mobile connections.
- Reduce a batch of event photos before emailing or sharing them with a team.
- Create lightweight review copies of high-resolution scans while retaining the originals offline.
What you can do here
- Supports JPG, PNG and WebP
- Adjustable quality slider
- Optional dimension resizing
- Batch compression with before/after size comparison
- Metadata stripping for extra savings
Limits and honest caveats
- EXIF metadata is stripped by default to save bytes.
- Avoid compressing an already-compressed file twice — repeated lossy passes amplify artefacts.
Common questions about Compress Image to Target Size (e.g. 20KB, 30KB, 50KB)
What is the best quality setting?
For photos, 80% is nearly indistinguishable from the original. For screenshots with text, keep 90–95%.
Is there a file-count limit?
No hard limit — the practical ceiling is your device's memory.
Should I lower quality or resize dimensions?
Resize when the image is physically larger in pixels than its display target; lower quality when you need further savings without changing width and height.
Why did a PNG not shrink much?
Simple PNG graphics may already be efficiently compressed. Photographs usually gain more from JPG or WebP-style lossy compression, while transparency or sharp text may justify keeping PNG.
