Compress any photo to an EXACT file size β€” type 200 KB and get 200 KB, on the first try. Email limits, web forms, visa applications, listing portals, forum avatars β€” they all want a photo "under X KB". Image Compressor hits that number precisely instead of guessing with a quality slider, so you never upload, fail, and retry again. HOW IT WORKS β€’ Pick photos from your library or the Files app. β€’ Type your target β€” 50 KB to 4 MB, or tap a preset. β€’ Tap Compress. A smart multi-pass search lands your photo just under the target at the best possible quality. β€’ Compare before and after with a slider, then save or share. WHY IMAGE COMPRESSOR? β€’ Exact-KB targeting β€” not a vague low / medium / high slider. β€’ Before/after comparison β€” check every pixel before you send. β€’ 100% on-device β€” your photos never leave your iPhone. No uploads, no servers, no account. β€’ No ads. Ever. β€’ Batch mode β€” up to 20 photos to one target in a single run (Premium). β€’ Metadata removal β€” strip EXIF and GPS location before sharing (Premium). β€’ JPEG or HEIC output (Premium). β€’ Savings history β€” see how many megabytes you reclaimed this week. β€’ Fully localized in 38 languages. FREE VS PREMIUM The free version includes 3 exact-size compressions per day with the full before/after preview. IMAGE COMPRESSOR PREMIUM Premium unlocks unlimited compressions, batch mode, metadata removal, and HEIC output. Premium is available as a weekly auto-renewable subscription with a 3-day free trial, or as a one-time Lifetime purchase. Subscriptions auto-renew until canceled. Cancel anytime in your Apple ID Subscriptions settings at least 24 hours before the renewal date.

Thock Meter

Read full description

Measure the "thock" of your mechanical keyboard. Thock Meter analyzes your keystroke sound in real time and turns it into a Thock score (0–100) β€” built for the custom-keyboard hobby. Lubed your switches, added case foam, tried a tape mod? Find out whether it actually got deeper and thockier β€” with a score and a live frequency profile, not just your ears. WHAT YOU GET (FREE) - Real-time Thock score just by typing - Live frequency profile from low-mid "thock" to high "clack" - Thocky / Balanced / Clacky / Pingy labels, plus Depth, Brightness and Cleanliness axes - Unlimited measurements; save up to 2 profiles THOCK METER PRO (one-time unlock) - Unlimited saved profiles - A/B compare: overlay two builds and see the Thock delta - Shareable score card: export your score and frequency profile as an image HONEST BY DESIGN This is a relative comparison tool for the same phone in the same position. It does NOT measure absolute loudness (dB/SPL). For the most stable read, type 10–20 letter keys with the phone ~15–20 cm away. It's tuned to characterize the tone (thock↔clack) of audible boards. PRIVACY Fully offline. Audio is analyzed on-device only β€” nothing is recorded, stored, or sent. No account, no network.
