Image tools
View all → Favicon Generator A proper favicon set used to mean a checklist: .ico for browsers, 180 for apple-touch, 192 and 512 for PWA installs, a manifest to tie it together, and the right link tags. Image HEIC to JPG Converter iPhone and recent Android phones shoot in HEIC by default: half the storage, but a format that Windows viewers, old Macs, online forms and many apps still choke on. Image Image Compressor Upload forms love to demand "under 1 MB" and never tell you how to get there. Image Image Cropper Crop product photos, avatars, passport-style headshots or screenshots down to exactly the region that matters. Image Image Resizer Every platform wants its own pixel size: avatars at 400, banners at 1920, thumbnails at 320. Image JPG to PNG Converter Need a PNG from a JPG? Image JPG to WebP Converter WebP is the modern image format the web runs on: the same picture typically comes out 25–35% smaller than JPG at comparable quality, it supports true transparency, and every current browser renders it natively. Image PNG to ICO Converter A real .ico file is not just a renamed PNG — it is a container holding several sizes so Windows can pick the crispest one for every context: 16 px for title bars and tabs, 32 px for desktop and Alt-Tab, 48 px for Explorer and shortcuts. Image PNG to JPG Converter PNG files are great for graphics but bulky for sharing. Image WebP to JPG Converter Downloaded an image from the web and ended up with a .webp your software refuses to open? Image
PDF tools
View all → Compress PDF Scanned contracts, photocopied certificates and camera-shot documents routinely weigh tens of megabytes and bounce off email attachment limits. PDF Delete PDF Pages Most of the time a PDF just needs a trim: drop the blank pages a scanner added, remove an outdated appendix, or delete the page with your home address before sharing a document. PDF JPG to PDF Sending twenty separate photos to a printer, an HR portal or a government form almost never works — they want one PDF. PDF Merge PDF Combining PDF files usually means emailing your documents to a conversion server and hoping they are deleted afterwards. PDF PDF to JPG Lots of systems accept images but not PDFs: chat apps that compress documents into unreadability, forms that only take JPG uploads, slides that need a quick preview image. PDF Rotate PDF Scanners and phone cameras love to hand you sideways or upside-down pages, and many PDF readers still make fixing them surprisingly awkward. PDF Split PDF A 200-page PDF is useless when you only need to send back pages 12 to 18. PDF
