Document & PDF Tools
Browser tools built by the Softlimes engineering team
Softlimes built this utility library to solve a recurring problem in daily engineering, marketing, and finance work: most free online calculators and converters bury a simple two-second task behind account signups, upload queues, or invasive tracking scripts. Worse, many legacy utilities upload your private PDFs, passport photos, API tokens, or financial numbers to an unknown remote server just to perform a calculation that modern browsers can run locally in milliseconds.
Every client-side tool in the Softlimes directory runs directly inside your web browser using native JavaScript, HTML5 Canvas, WebAssembly, and the W3C Web Crypto API. Whether you are shrinking an identity photo to an exact 20 KB portal limit, inspecting a JWT authentication token during an outage, calculating net salary tax deductions, or auditing landing page metadata before launching a Google Ads campaign, your input stays in your local device memory from start to finish.
Image Compression, Format Conversion & Background Removal
Government application portals, university admission systems, and e-commerce storefronts enforce strict byte ceilings that default smartphone and desktop exports regularly fail. Our target-size image compressors, format converters, and browser retouching utilities use iterative binary search over quantization tables and canvas dimensions:
- Exact Kilobyte Compressors: Meet strict upload limits with presets for Compress Image to 20KB, 50KB (for NADRA, HEC, FPSC, PPSC, and visa forms), 100KB, 200KB, 500KB, and 1MB.
- Background & Watermark Cleanup: Export transparent PNGs with our AI Background Remover (powered by on-device IS-Net segmentation), clean up camera date stamps with the Watermark Remover, strip GPS location tags in the EXIF Metadata Remover, or convert files in the JPG & PNG to WebP Converter and Online Video Editor.
Developer Utilities, Cryptography & Server Config Generators
Modern web and mobile architectures depend on clean data serialization and strict cryptographic standards. When a webhook fails signature verification or an API gateway rejects a malformed payload, pasting production data into a server-logged formatting site exposes customer records and secret keys.
Our JSON Formatter & Validator (RFC 8259), JWT Decoder (RFC 7519), Regex Tester, SHA-256/512 Hash Generator (FIPS 180-4), Base64 Encoder/Decoder, and UUID v4 Generator run inside your local browser tab. You get exact byte lengths, line-level syntax diagnostics, and copy-ready output without exposing credentials outside your workstation.
Technical SEO, Website Audits & Google Ads Landing Page Checks
Sending paid search or organic traffic to a slow or misconfigured page wastes media budget. Our SEO and web audit utilities let you check live URLs in the Free Website Audit Tool, estimate development budgets in the Website Development Cost Calculator, generate Schema.org JSON-LD Markup, preview desktop and mobile SERP snippets in the SEO Meta Tag Generator, and inspect server security in the SSL Certificate Checker and HTTP Security Headers Checker.
Pakistan FBR Salary Tax, Zakat & Financial Calculators
Operating profitable campaigns and managing company payroll require exact marginal math rather than rough averages. Calculate monthly withholding tax and net take-home pay under Section 149 of Pakistan's Income Tax Ordinance with our Pakistan Salary Tax Calculator and Take-Home Salary Calculator. You can also value liquid cash, gold, and silver against the 7.5-tola gold (87.48g) and 52.5-tola silver (612.36g) thresholds in the Nisab Calculator and Zakat Calculator, or format bank cheque amounts with the Number to Words Converter.
