Ideal Image Sizes for Blogs, Portfolios, and Shops

Discover ideal image sizes and formats for blogs, portfolios and online shops, and learn how to prepare them using Compress It Small image tools.

Images are often the heaviest part of a web page. Large, unoptimised photos can slow down your site, hurt search rankings and frustrate visitors on mobile connections. The goal is to keep visuals sharp while loading quickly. In this guide we outline practical image sizes and how to reach them using the Compress It Small image tools.

1. Choose the right width for your layout

For most modern websites you do not need 4000-pixel-wide images. A simple rule that works for many layouts is:

  • Full-width banner on desktop: 1600–1920 px wide.
  • Standard blog content images: 1000–1200 px wide.
  • Thumbnail or grid cards: 400–800 px wide.

If your theme has a fixed content width, check it once and then export everything slightly larger than that. There is no benefit in uploading files far wider than the largest container on your site.

2. Pick the right format: JPG, PNG or WebP

Different formats have different strengths:

  • JPG: best for photographs and complex scenes with gradients.
  • PNG: best for logos, icons and graphics with transparency or sharp edges.
  • WebP: modern format that can offer smaller sizes for both photos and graphics.

On many platforms, JPG is still the safest default for photos. You can use the image converter and compressor to switch between formats and see which one gives you the smallest size at acceptable quality.

3. Target file sizes for faster pages

Instead of guessing, it helps to work with clear targets:

  • Hero or banner image: ideally under 300 KB, maximum 500 KB.
  • Regular content image: 80–200 KB.
  • Thumbnail or product grid image: 30–100 KB.

These are not strict rules, but if most images stay within these ranges your pages will feel fast even on slower connections.

4. Use Compress It Small to resize and compress in one step

On the Compress It Small image tools page you can:

  • Resize images to a specific width for your theme.
  • Choose a quality slider to balance clarity and size.
  • Convert bulky PNGs to lighter JPGs where transparency is not needed.

Upload a sample image, set the desired width, then adjust quality until you reach an acceptable balance. Use that as your baseline setting for future uploads.

5. Build a simple image workflow

For blogs, portfolios and shops, consistency matters more than perfection. Pick one or two standard widths for all content images, stick to a format per use case, and always run pictures through an optimiser before uploading.

Over time, this habit will keep your media library clean and your site quick, without sacrificing the visual impact of your work or products.

Ideal image dimensions: practical ranges for blogs, portfolios, and shops

There is no single “perfect” size, but there are safe ranges that balance sharpness with fast loading. Use the smallest dimensions that still look good at your intended display size. Oversized images slow down pages and waste bandwidth, especially on mobile.

Blogs and articles

  • Featured/hero image: ~1200–2000px wide (choose based on your theme’s layout)
  • In-article images: ~1000–1600px wide (often enough for full-width content)
  • Thumbnails: ~300–600px wide (depending on card/grid design)

Portfolios

  • Project previews: ~1200–1800px wide, keep file size controlled for smooth scrolling
  • Detail shots: ~1600–2400px wide only when users will zoom

Shops and product listings

  • Listing images: ~800–1200px wide (fast grid browsing)
  • Product detail images: ~1200–2000px wide (balance clarity with load time)

After choosing dimensions, compress using Image Tools and validate that your final file sizes are reasonable (typically a few hundred KB for most use-cases). If you are embedding these images into PDFs for submissions, convert with JPG to PDF and then finalize with PDF Compressor.

File-size targets and how to hit them reliably

For many sites, image file size matters as much as image dimensions. As a practical starting point:

  • Thumbnails: often 50–150 KB
  • Standard in-article images: often 150–400 KB
  • Large hero images: often 250–600 KB (depending on complexity)

To hit these targets without guesswork, resize first, then compress. If you compress without resizing, you often trade away quality while keeping too many pixels. For a step-by-step workflow, see how to reduce image size without losing quality.

Image size has two components: pixels and format

When an image file is “too big,” it is usually because of (1) too many pixels and/or (2) the wrong format. A 4000×3000 photo is excellent for printing, but it is overkill for a website hero image or an email attachment. The same image saved as PNG can be several times larger than JPG because PNG is lossless.

Start by choosing the correct format using the decision logic from JPG vs PNG and then reduce dimensions for your actual use-case. If you need a quick, guided workflow, use Image Tools and keep your output targeted for screens.

A practical workflow for “small but sharp” images

  1. Resize first: set a realistic width for the target (blog, portfolio, product listing).
  2. Choose the right format: use JPG for photos, PNG for simple graphics that need transparency.
  3. Compress gradually: reduce quality in small steps and check at 100% zoom.
  4. Strip unnecessary data: metadata is not always huge, but removing it improves privacy and can reduce size.

After optimizing images, you can convert them into a lightweight PDF using JPG to PDF—useful for portfolios, forms, and multi-photo uploads.

A simple sizing strategy for consistent quality

The easiest “one-size-fits-most” strategy is to choose 2–3 standard widths that match your layout (thumbnail, standard, hero), then stick to them. This keeps your site consistent and prevents accidental multi‑MB uploads.

  • Thumbnail width: for grids and cards
  • Standard width: for most in-article images
  • Hero width: for featured banners and landing sections

Once you pick your sizes, compress with Image Tools and reuse them across posts and pages. This consistency makes your content load faster and feel more professional.

Real-world examples: choosing the smallest output

When you optimize an image for the web, you are balancing three things: perceived sharpness, load time, and compatibility. The most common failure mode is compressing aggressively while leaving the image at a huge pixel size. The better approach is to decide the maximum display width first (for example, the width of your content column) and resize to that. Once the image is at the right dimensions, compression becomes far more effective and quality holds up better.

A practical workflow is: resize → choose format → compress → verify. Use Image Tools to do the resizing and compression, then preview the image at 100% zoom. If the image contains text (screenshots, UI), keep quality slightly higher than you would for a photo. If the image is a photo, JPG will often be smaller; if you need transparency or crisp edges, PNG may be better—see the JPG vs PNG breakdown.

If your final goal is an upload to a form or a submission portal, convert optimized images into a PDF using JPG to PDF. That creates a single clean document and lets you do a final size pass with PDF Compressor. This is especially useful when a portal accepts one file but you have multiple photos or screenshots to include.

Finally, do not ignore naming and context. Search engines and accessibility tools benefit from descriptive alt text and filenames. Users benefit from images that load instantly. Those small signals add up, especially across many pages and posts.
