Need to reduce a photo below 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, 2 MB, or a custom file-size limit? Image Compressor: KB/MB Limit lets you choose the maximum size first. The app then automatically optimizes the image to preserve the highest practical visual quality while keeping the result below your selected limit. NO PERCENTAGE GUESSING You do not need to experiment with quality percentages, dimensions, or compression settings. Select the required limit in KB or MB and let the app handle the technical adjustments. HOW IT WORKS Choose a maximum file size. Select one or multiple photos, or take a new photo. Let the app optimize quality, dimensions, compression, output format, metadata, and orientation when needed. Review the verified final file size. Save or share the result. MADE FOR EVERYDAY UPLOADS Prepare smaller images for websites, online forms, email attachments, marketplaces, e-commerce listings, content platforms, business tools, and other services with file-size restrictions. KEY FEATURES • Preset sizes including 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, and 2 MB • Custom limits in KB or MB • Single and multiple-photo processing • Verified output file size • Highest practical quality below the selected maximum • No unnecessary enlargement or re-encoding when an image already fits • Local processing on your device • No account required • Photos are not uploaded to a server Every image compresses differently.
