Why browser-local beats blind upload
Many popular utilities ask you to upload images or PDFs to their servers. TCB Tools processes file jobs in your browser whenever the tool says so — so drafts, client assets, and internal docs never need to leave your device for basic compress / resize / merge / split work.
TCB Tools vs TinyPNG-style upload compressors
Upload compressors are excellent at smart lossy codecs. Tradeoff: your file travels to a third party. TCB Image Compressor runs on Canvas in-tab, shows before/after, supports target KB mode, HEIC ingest, and ZIP batch download — with honest limits printed on the dropzone.
TCB Tools vs Smallpdf-style PDF suites
Hosted PDF suites offer deep features and accounts. TCB PDF tools stay client-side with pdf-lib + pdf.js thumbnails for merge/split, ZIP for multi-part outputs, and clear page/file caps. Choose hosted tools when you need OCR, e-sign, or server-grade Ghostscript compression.
TCB UTM Builder vs server campaign builders
Official and SaaS UTM builders are fine. Ours keeps the form fast, shareable via URL state, and paired with related marketing calculators (ROAS, CPC, CPM, CTR, budget) so campaign setup and math live in one product.
