Remove Location and Camera Data Before Sharing Photos
A phone photo can carry GPS coordinates, device model, and timestamps. How to confirm what is in the file, strip it with a re-encode, and verify the copy you actually share.
Guides
Straight answers about image files: what changes when you compress, when a format is the wrong choice, and how to get a batch of images to behave. Every procedure here maps to a tool that runs in your browser.

LinkedIn Image Crops: Ratios and Safe Areas That Survive Every Placement
How LinkedIn crops each placement, the safe areas that survive mobile and desktop, and a repeatable export workflow for profile, banner, logo, and feed images.
Watermarking
Add a Logo Watermark to a Folder of Photos
A repeatable batch workflow for stamping one logo onto a folder of images: preparing a transparent PNG, keeping the mark proportionate, and choosing placement that survives a crop.

Product Image Requirements for Amazon, eBay and Etsy
The rules marketplaces share, the ones that differ, and a workflow for producing compliant main images and gallery photos without guessing at pixel limits.
Troubleshooting
Your Upload Was Rejected for Size: Fix It in Order
The error says size, but the rule may be bytes, pixels, or format. Read the rejection, fix the earliest constraint first, and stop recompressing when the limit is actually dimensions.
Formats
PNG to JPG: What Happens to Transparency
A transparent pixel is not white, and JPEG cannot store one. How compositing works, why logos sometimes get black boxes, and how to pick a background that hides the seam.
Formats
Why Transparent Areas Turn Black in JPEG
JPEG has no alpha channel, so transparency has to become a color. Black usually means a default fill or a hidden black under transparent pixels. How to diagnose and choose the replacement.
Resizing
Resize an Image to Exact Pixel Dimensions
Why the aspect lock turns width and height into a bounding box, when to turn it off, how DPI misleads people, and a repeatable way to hit an exact pixel size.
Formats
Image Formats for Print vs Web
Resolution, color mode, bit depth, and file format all change when the destination is paper. What to keep in the master and what to export for each target.
Resizing
Why Resized Images Look Blurry
Blur after resizing usually comes from resizing in the wrong direction, resizing too many times, or exporting too small for the display. A diagnostic order that finds which one.
Formats
WebP Support in 2026 and When You Still Need a Fallback
Browser support is no longer the problem. Here is where WebP still fails, how to add a fallback without doubling your workload, and when JPEG remains the safer delivery format.
Web performance
Shrink Images for a Website Without Degrading Them
Match export dimensions to the space an image actually occupies, choose a format that survives re-encoding, and avoid the two mistakes that make web photos look soft.
Formats
Why Your PNG Is So Large, and What to Do Instead
PNG is doing exactly what it promises: keeping every pixel. Here is where the bytes go, how to confirm the cause, and which format or control actually reduces the file.
Get Photos Under Email Attachment Limits
Why a photo that fits on disk still gets rejected, how much space encoding overhead takes, and a two-step resize-and-compress workflow that keeps photos readable in the inbox.
Compression
Lossless vs Lossy Image Compression
What lossless actually preserves, why photographs resist it, where generation loss comes from, and how to tell which kind of compression a tool is using.
Performance
What Actually Makes Website Images Slow
Oversized dimensions, the wrong format, and images that should never load are the usual causes. A diagnostic order that finds the real problem before you recompress anything.
Compression
JPEG Quality Settings: What the Number Actually Changes
Why 80 is not 80 percent, which artifacts appear as quality drops, and how to choose a setting that survives re-encoding.
Compression
How to Compress a JPEG to 200 KB
A 200 KB ceiling is roomy for a web-sized photo and tight for a full-resolution one. How to hit the target, which settings matter, and how to judge whether the result still holds up.
Compression
How to Compress an Image to 100 KB Without Ruining It
A practical guide to hitting a 100 KB upload limit: which settings matter, how far you can downscale, and what to do when the target is genuinely impossible.
Formats
PNG vs WebP vs JPEG: Which Format Should You Use?
How the three formats store pixels, when WebP actually wins, why PNG cannot be quality-compressed, and the conversion mistakes that quietly damage images.
Resizing
How to Resize an Image Without Losing Quality
What resampling actually does, why DPI is not a quality setting, how to pick pixel dimensions for print and screen, and the mistakes that make images soft.
Watermarking
How to Add a Watermark to Multiple Images at Once
A practical batch watermarking workflow: position, size, opacity and rotation settings that stay readable, plus what a visible watermark can and cannot protect.

Why Your Photos Are Sideways, and How to Fix EXIF Rotation
EXIF orientation explains why the same photo looks upright on your phone and sideways on a website. How to diagnose it, fix it permanently, and what metadata you lose.
