Compress Image to 100 KB, 50 KB, or 200 KB (Exact Target Size)
Shrink passport photos, signatures, and ID scans to strictly under 100 KB (or 50 KB / 200 KB) locally in your browser with zero uploads.
Private tools for files that shouldn't leave your computer.
Fifteen free utilities across 4 categories—Image Tools Suite, Labels & Print, AI & Documents, and Data & Developer. They run in your browser, so your files are never uploaded.
Verifiable Local Privacy & Binary Precision
Most online converters upload your confidential shipping labels, family photos, and CSV databases to remote server queues. Vexolora processes your files directly inside your browser's volatile memory (RAM) using standard Web APIs (ArrayBuffer, DataView, DOMParser, and HTML5 Canvas).
- ✓ Zero Server File Storage: Core tools never upload your files—verify it yourself in your browser's Network tab.
- ✓ True Binary Header Editing: Our 300 DPI Scrubber writes 9-byte PNG
pHYschunks and JPEGJFIFheaders without re-encoding pixels. - ✓ Batch & ZIP Ready: Process up to 100 images at once and download a single standards-compliant ZIP archive.

How to Use the Compress Image to 100KB / 50KB
1. Step 1: Drop Your JPG, PNG, or WebP Images
Drag and drop one or up to 100 images into the compressor, click Choose files, or paste from your clipboard.
2. Step 2: Select Target KB Mode (50KB / 100KB / 200KB) or Manual Quality
Pick "Target ≤ 100 KB" (or ≤ 50 KB / ≤ 200 KB) for strict portal limits, or choose "Manual Quality Slider" for custom compression.
3. Step 3: Choose Output Format (JPG or WebP)
Select JPG for universal form uploads (passports, visas, job portals) or WebP for maximum website speed.
4. Step 4: Click Compress Image(s)
Trigger the 3.5-second binary-search quantization engine to find the highest visual quality under your byte ceiling.
5. Step 5: Verify Byte Savings Percentage & Visual Sharpness
Check the green percentage saved badge (e.g., -74%) and inspect the live preview.
6. Step 6: Download Compressed Image(s) or Batch ZIP
Save your sub-100KB file, download all files as a ZIP archive, or send to the 300 DPI Scrubber.
Frequently Asked Questions
1. How does the tool guarantee my image is under 100 KB?
It runs an iterative binary search over JPEG quality (and gentle dimension scaling if needed) until the encoded Blob size is strictly below 102,400 bytes.
2. Can I switch the target to 50 KB or 200 KB?
Yes. Use the Compression Mode dropdown to select Target ≤ 50 KB, Target ≤ 100 KB, or Target ≤ 200 KB.
3. How do I compress an image to under 100 KB (or 50 KB) without making it blurry?
Select "Target ≤ 100 KB" (or "Target ≤ 50 KB") in the Compression Mode dropdown. Our engine runs a multi-step binary search over encoder quality so your file lands just under the limit while keeping maximum detail.
4. Is it safe to compress passport scans, ID cards, or signatures here?
Yes. All compression runs 100% locally in your browser RAM. Your sensitive identity documents are never uploaded to a server.
5. What happens if a huge 20 MP photo cannot fit under 50 KB by quality alone?
If minimum quality still exceeds 50 KB due to massive pixel dimensions, the engine automatically steps down pixel dimensions proportionally until the strict byte target is met.
6. Why does converting a PNG to JPG or WebP shrink the file size by 75% to 85%?
PNG uses lossless compression, which creates large files for photographs. Encoding photographic content as high-quality JPG or WebP removes imperceptible chroma noise and strips metadata bloat.
7. Does compressing an image remove hidden EXIF and GPS metadata?
Yes. Re-encoding through the compression pipeline strips bulky EXIF camera tags, GPS coordinates, and embedded thumbnails—which alone saves 30 KB to 65 KB.
8. Can I batch compress an entire folder of website or product images?
Yes! Drop up to 100 images at once and click "Download ZIP" to save the entire compressed batch.
9. What quality setting is best for general website SEO and Core Web Vitals?
A manual quality of 75% to 82% (or Target ≤ 200 KB in WebP/JPG format) typically cuts image weight by 65%+ with zero visible degradation.
