Why Compress to an Exact Size?
Most image compressors give you a quality slider and hope for the best. CompressNow lets you pick a precise target — 10KB, 50KB, 100KB, 500KB — and hit it exactly. That matters when you're dealing with strict upload limits: passport photos must be under 100KB, email attachments under 25MB, and Discord avatars under 8MB.
