Frequently Asked Questions

How do I compress an image to under 100KB without losing readability?
Our smart bitrate and compression algorithm balances pixel dimensions and image encoding. When you select the 100KB preset, the compressor iteratively adjusts quantization and downsizes slightly if necessary, ensuring fine text on certificates or facial features on passport photos remain sharp and easily readable while staying strictly under 100KB.
Can I compress images to other strict limits like 50KB or 200KB?
Yes! You can choose from our preset chips for 50KB (strict government forms), 100KB (general job portals), 200KB, or 500KB. You can also adjust custom target sizes in our image suite to meet any exact upload specification.
Which image formats can be compressed to 100KB?
NeatCompress supports JPG/JPEG, PNG, WebP, and iPhone HEIC/HEIF files. You can output compressed files in standard JPEG for maximum compatibility with government portals, or WebP for optimal compression ratio.
Is it safe to compress sensitive identity and passport photos here?
Completely safe. Unlike cloud-based photo resizers, NeatCompress processes all image files 100% locally inside your browser using client-side JavaScript and WebAssembly. Your ID cards, diplomas, resume photos, and personal documents are never uploaded to any server or third party.
Why do some portal upload systems reject my 100KB image?
Some legacy portals check strict decimal bytes (100,000 bytes) rather than binary kilobytes (102,400 bytes), while others enforce specific aspect ratios (like 3:4 or 1:1 square) or file types (JPEG only). The preset targets 100,000 bytes; check the actual result, required dimensions and accepted formats against the current portal rules.
