Helpful guides for this workflow
The tool handles the processing, but these guides explain the choices around it: format decisions, upload-limit tradeoffs, ecommerce prep, and when resizing or compression is the better first move.
JPG vs PNG vs WebP: which image format should you actually use?
If you only have a few seconds, use JPG for photos, PNG for screenshots and transparency, and WebP for modern web delivery when you want smaller files at the same visual quality. This guide explains why those defaults work, when to break them, and which settings are safest for common workflows.
How to resize product images for Shopify without making them look cheap
Shopify product images need more than just smaller file size. They need consistent dimensions, practical compression, and enough clarity to support product confidence without slowing the store down.
How to compress images for email without making them look blurry
Email is one of the easiest places for image workflows to go wrong. Files are often larger than they need to be, but over-compressing them can make the result look cheap or hard to read. This guide explains the tradeoff in a practical way.
When should you resize an image instead of compressing it?
A lot of people reach for compression when the real issue is oversized dimensions. This guide explains how to tell whether you should resize, compress, or do both, and in what order.
How to reduce image file size for Instagram and social media
Every major social platform re-compresses your images automatically. The best way to preserve quality is to upload at the correct dimensions and let the platform work from a good source. This guide covers what that looks like for each major network.
How to convert HEIC photos to JPG
iPhones capture photos in HEIC format by default because it uses less storage than JPG at the same quality. But HEIC has compatibility problems with many websites, software, and sharing workflows that still expect JPG. This guide explains how to convert quickly and what happens to quality when you do.
How to compress images for a WordPress website
WordPress handles some image optimization automatically, but it does not do everything. Understanding what WordPress does and does not do helps you decide what to prepare before uploading and where a plugin might actually help.
What is DPI and does it actually matter for web images?
DPI is one of the most misunderstood settings in image workflows. For web images, it almost never matters. For print and PDF, it does. This guide explains the difference clearly and tells you what to actually pay attention to.
How to batch resize images without losing quality
Batch resizing lets you prepare dozens or hundreds of images at once instead of one at a time. Getting the target dimensions right before you start is the most important decision in the process. This guide explains how to do both correctly.
How to compress images for Google Slides and PowerPoint
A 180 MB PowerPoint that refuses to attach to an email, or a Google Slides deck that takes thirty seconds to load each slide — the cause is almost always the same thing: full-resolution photos and screenshots dropped in at their original size. Compressing those images, either before they go into the deck or after it has already ballooned, solves the problem in a few minutes and almost never visibly hurts the slide quality.
How to reduce image size on iPhone without losing quality
A single iPhone photo can be 4 to 8 MB on a recent model. That is fine for the camera roll, but too large for many job application portals, school upload systems, and corporate email servers. The iPhone has several built-in ways to reduce image size, and choosing the right one for your situation usually keeps the quality good enough that nobody notices the difference.
How to prepare product images for Amazon and eBay
Amazon will hide or suppress a listing whose main image does not meet its policy. eBay will accept almost any image but rank listings with poor photos far below those with sharp, well-prepared ones. Both outcomes hurt sales. The image requirements are not difficult to meet, but they are specific — and they differ enough between the two platforms that one set of files usually cannot serve both without preparation.
Why your PDF looks pixelated when printed
You open the PDF, it looks crisp on your monitor, you send it to the printer — and the output is fuzzy, jagged, or visibly pixelated. The text on screen was sharp; the printed text has soft edges. The photos that looked clean now show blocky artifacts. Almost every case of this comes down to one of three things: low-resolution source images, aggressive compression at some earlier step, or a mismatch between the PDF effective resolution and what the printer actually needs.
How to reduce file size before uploading to a job application portal
You hit the upload button on a job application portal, the page sits for a few seconds, and then nothing happens — or worse, you see a vague error like File too large or Unsupported format. Most job application portals enforce strict size limits, sometimes as low as 1 MB per file, and they enforce them silently. The file uploads but never reaches the recruiter. Knowing how to prepare files for these portals is the difference between getting reviewed and getting filtered out before a human ever sees the application.
What is WebP and should you convert your website images to it?
WebP has been around since 2010, and as of 2026 it is supported by every major browser. Despite that, most websites still serve JPG and PNG everywhere, and most of those websites would load measurably faster — and rank slightly better on Core Web Vitals — if they switched. This guide gives you the actual numbers and a clear decision framework for whether your site should convert.
How to compress a screenshot before sending it in Slack or Teams
A screenshot of a full 4K monitor can easily be 3 to 6 MB. Send a few dozen of those in a busy Slack channel during a single product review and you have noticeably slowed down the channel for everyone — slower scroll, slower image loads, more storage burn on your team plan, and a more cluttered search experience when somebody tries to find an old conversation later. Compressing screenshots before sending is a small habit that pays off for the whole team.
How to prepare images for a Wix or Squarespace website
Both Wix and Squarespace handle image optimization automatically once a file is uploaded — but only as well as the source allows. Upload a 12 MB phone photo and the platform will compress and resize it for browser delivery, but it still has to ingest, store, and process that 12 MB file in the first place. Sites with hundreds of poorly-prepared images end up slower, more expensive to host, and harder to manage than they need to be.
