Guides, grouped by problem.
The questions behind the tools - answered plainly, tested honestly, and each ending in a fix that runs in your browser. New guides ship several times a week; the blog lists everything newest-first, and the glossary defines the jargon.
Make files smaller
Email limits, upload caps, and oversized exports.
- Why Is My Scanned Document So Large? A one-page scan hitting 5-10MB isn't a broken scanner - it's the default resolution and color mode doing exactly what they're set to do. What actually shrinks it.
- How to Compress a Photo Without Losing Quality Compression only looks lossless when you pull the right two levers - quality setting and resolution - in the right order. Here's the honest, non-magic version.
- How to Compress Photos for Email (Without Losing Quality) Email caps attachments around 20-25MB, and phone photos burn through that fast. The two levers that actually shrink photos - and the settings that keep them looking sharp.
- Why Is My PNG So Large? (And What Actually Shrinks It) A 4MB screenshot isn't broken - it's how PNG works. What makes PNG files huge, which fixes actually work, and the 'compression' advice that does nothing.
iPhone & HEIC
Why iPhone photos misbehave elsewhere, and the fixes.
- Why Do My iPhone Photos Look Different on Android? It's rarely the phone's fault. Wide-gamut color profiles, a HEIC-to-JPG detour along the way, and screen calibration each shift color a little - here's which one is actually happening.
- iPhone Photos Too Big to Upload? Here's How to Fix It Upload forms reject iPhone photos for two different reasons - file size and HEIC format - and the fix depends on which one you hit. How to tell them apart and shrink the photo properly.
- HEIC Won't Open on Windows? Every Fix, Explained Why Windows can't open iPhone HEIC photos, the two-minute fix, and how to stop it happening again - including the free codec catch Microsoft doesn't advertise.
Photo privacy & metadata
What your files quietly reveal, and how to clean them.
- Do Screenshots Contain Metadata? Usually not the GPS and camera EXIF a phone photo carries - screenshots are captured differently. What they can still carry, and the bigger risk that has nothing to do with metadata at all.
- How to Blur a Face in a Photo (No App Install) Drop the photo in a browser tab, let it find the face automatically, pick pixelate or blackout, download. No app, no account, no upload of the original.
- Selling Online Safely: What Your Product Photos Reveal Marketplace photos leak two different ways - hidden GPS data in the file, and visible clues in the frame. A pre-listing check for both before you post.
- What Is EXIF Data? What Your Photos Reveal About You EXIF data is the hidden information saved inside every photo - date, device, camera settings, often GPS location. What it contains, who can see it, and how to check and remove it.
- How to Remove Location Data From iPhone Photos Your iPhone writes GPS coordinates into every photo. Here's how to check what a photo reveals, remove it before sharing, and stop recording it - without uploading the photo anywhere.
- AI Images Can Carry Your Prompt: What's Inside a Generated PNG Many AI image tools write your full prompt, seed, and settings into the file itself. How to see what a generated image is carrying - and share the image without shipping your prompt.
Formats, explained
JPG, PNG, WebP, and when each one is the right call.
- Why Does My Transparent PNG Turn Black When Converted to JPG? JPG has no transparency channel at all - something has to fill the see-through areas. Black shows up when a converter never bothered to choose, not because JPG prefers it.
- JPG vs PNG vs WebP: Which Format When (a Practical Guide) The three formats make different promises: JPG trades detail for size, PNG keeps every pixel, WebP does both jobs smaller. A working decision guide with the edge cases.
Safety & trust
What online tools actually do with your files - and how to tell.
- Are Online Image Converters Safe? What Happens to Uploads Online converters are usually safe for casual images - but 'convert' means 'upload to a stranger's server' unless the tool runs in your browser. How to tell the difference, and when it matters.
