Reduce PNG files to a practical upload size while keeping them usable for screenshots, logos, icons, and transparency graphics.
Drag in one file or a full batch. The uploader handles typical PNG workflows such as email attachments, website assets, and portal submissions.
Pick 100KB when you need to meet a form limit, shrink page weight, or stay under an attachment cap. The engine balances compression ratio and visual quality automatically.
Download the compressed output individually or as a ZIP archive, then use it immediately for uploads, publishing, sharing, or storage cleanup.
PNG files at 100KB retain good quality for web display and document sharing. Fine text and subtle gradients may show slight artifacts at full zoom.
For photographs, 100KB works well at web resolution (up to 1200px wide). Printed output may show some softness at larger sizes.
PNG is commonly used for screenshots, logos, icons, and transparency graphics. Typical originals land around 1–10 MB, so compressing to 100KB is most useful when you need to meet a strict upload or performance target.
These are the most practical reasons people compress PNG files to 100KB.
Fit over 200 PNG files under the 25 MB email limit. At 100KB each, batch sharing becomes practical for any email provider.
100KB images load in under 0.5 seconds on 3G connections, keeping your Largest Contentful Paint (LCP) score in the green zone for Core Web Vitals.
Government portals, job applications, and university submissions often cap uploads at 100KB. Compress to comply without losing readability.
Built for target-size compression, repeatable results, and practical delivery workflows.
Upload and compress multiple PNG files to exactly 100KB simultaneously. Download all results individually or as a single ZIP archive.
Your files are processed securely and deleted automatically after compression. Nothing is stored, indexed, or shared with anyone. Ever.
Our algorithm iteratively adjusts compression to land as close to 100KB as technically possible — not an approximation, but a precise target.
Compress files directly in the browser. No plugins, desktop apps, or extra setup are required.
Files are processed securely and deleted automatically after compression, which keeps upload workflows private and easier to trust.
Digital signature uploads for banking KYC, mutual-fund CAMS/KFin onboarding, and demat account opening all cap at 100 KB for PNG files. PNG is preferred over JPG here because the compression is lossless — signature strokes stay clean at any zoom level. Hitting 100 KB usually means posterising the scan to 8 colours.
PNG không mất dữ liệu - định dạng tệp không thể loại bỏ dữ liệu hình ảnh. Để đạt được mục tiêu kích thước nhỏ, máy nén phải (a) giảm bảng màu từ truecolor 24 bit xuống 8 bit (256 màu) hoặc 4 bit (16 màu), giúp giảm kích thước 40-70% nhưng làm phẳng độ dốc và có thể phối màu các vùng mịn hoặc (b) chuyển hoàn toàn mã hóa sang JPG bị mất dữ liệu (từ bỏ tính minh bạch và đảm bảo không mất dữ liệu của PNG). Đối với ảnh chụp màn hình, sơ đồ và logo có màu sắc hạn chế, tính năng giảm bảng màu sẽ hoạt động hiệu quả. Đối với nội dung ảnh được lưu dưới dạng PNG, chuyển đổi JPG thường mang lại chất lượng trên mỗi kilobyte tốt nhất ở mục tiêu này.
Every compressor makes a trade-off between file size and visible quality. Here's what happens under the hood, and how to get the smallest file that still looks the way you need it to.
The drop zone accepts single images or batches. Free-tier uploads are limited to 10 MB per file — enough for most phone photos and standard web images. Pro handles files up to 1 GB and batches of up to 20 at once. Every filename is preserved.
The algorithm iterates the quality setting until the result lands close to 100KB, then stops. That means the output isn't a fixed quality preset — it's calibrated to the size target, so the same tool produces bigger visible quality on a small source and heavier compression on a large one.
The compressed file downloads immediately once ready — typically a couple of seconds per image. Preview the output at full size before shipping it: aggressive size targets on large sources can introduce visible blocking or blur that\'s worth catching before submission. Both the upload and the compressed output are deleted from our servers within 30 minutes.
Most compressors ask you for a "quality" slider and expect you to guess. Portals and forms don\'t care about your quality slider — they care whether the file is under 100KB. Targeting a specific size directly is a much more honest workflow: you tell the tool the byte count you need, it does whatever compression is required to hit that number, and you preview the result to make sure the quality is still workable.
Six specific scenarios where hitting an exact size ceiling is the actual job.
Visa applications, passport renewals, driving-licence uploads, and tax portals routinely cap photo uploads at very specific byte counts — 100KB is a common ceiling. Hitting it exactly means one upload attempt instead of five, and no rejection email 48 hours later.
Gmail caps attachments at 25 MB, corporate systems often lower. A stack of high-res photos blows past the limit fast. Compressing each to 100KB keeps the email deliverable without splitting into three follow-ups.
Core Web Vitals treat page-weight seriously — every hero image over about 100 KB drags your Largest Contentful Paint score. Compressing to 100KB before upload keeps individual images inside the sensible-web-image range.
WhatsApp, Signal, and Telegram re-encode images on upload — the recipient sees whatever quality the app decided on. Compressing to 100KB upfront means you control the trade-off rather than leaving it to the app\'s default (which is usually more aggressive than you would pick).
A 500-photo trip in RAW or full-res PNG eats gigabytes. Batch-compressing to 100KB preserves the memories while making the archive cloud-storable, backup-friendly, and searchable without dragging your library app to a crawl.
Photo-print services, calendar makers, and merchandise platforms often specify a max file size per image, then reject anything above. 100KB is a common target that hits their cap while leaving enough quality for standard print sizes.
