Best Free Image Tools Online (Compress, Resize, Convert)

Image jobs that actually matter

Most people don’t need a full photo editor. They need four outcomes:

1. Smaller files for email, CMS, or WhatsApp
2. Correct dimensions for avatars, banners, and thumbnails
3. Format conversion (HEIC → JPG, PNG → WebP)
4. Privacy cleanup (strip GPS / EXIF before sharing)

Here are free browser tools that cover those jobs well.

Best free tools by task

Compress images without a desktop app

Compress Image shrinks JPG, PNG, and WebP with quality and max-dimension controls. Use stronger compression for blog hero images; stay gentler for product photos where detail sells.

Resize for platforms and UI

Resize Image is the right first step when a site rejects “image too large” or your headshot needs a square crop downstream. Resize then compress for the best size/quality tradeoff.

Remove EXIF / GPS data

Phone photos often embed location and device metadata. Remove EXIF metadata helps before you post screenshots or travel photos publicly.

Convert formats

Browse AllToolHub’s image category for conversion and effect utilities when a CMS only accepts JPG or you need WebP for performance.

Recommended workflows

Blog or docs image

1. Resize longest edge to ~1600–2000px if the design doesn’t need more
2. Compress with a web preset
3. Prefer WebP when the platform supports it

Social avatar

1. Resize to the platform’s exact pixel size when known
2. Light compression only—faces show artifacts quickly

Client proof / portfolio

1. Strip EXIF if location privacy matters
2. Mild compress so quality still looks intentional

Quality checklist

• Zoom to 100% on text-in-image (memes, UI shots) after compress
• Keep a lossless original in a “masters” folder
• Don’t recompress the same JPG ten times—generation loss adds up
• For transparent logos, verify alpha still looks clean after conversion

FAQ

Is free image compression “lossy”?

Often yes—and that’s fine for photos on the web. Lossy compression removes detail humans rarely notice at normal viewing sizes. Keep masters when print or heavy crop is possible.

What’s better: resize or compress first?

Usually resize first (fewer pixels), then compress. Compressing a 6000px photo you will display at 800px wastes time and can look worse.

Can browser tools handle HEIC from iPhones?

Support depends on the specific tool and browser capabilities. If HEIC fails, convert on-device to JPG once, then compress in the browser.
