Free online SVG optimizer

Optimise SVG files without turning them into pixels

Reduce safe SVG structure directly in your browser while preserving the vector format, viewBox and intended dimensions. Process up to 25 files and download the completed batch in one ZIP.

Built for vector artwork

A careful SVG optimizer for logos, icons and illustrations

SVG is XML-based vector artwork, so it needs a different process from JPEG, PNG or WebP. ImageOptimise validates the document, removes active external behaviour and reduces safe structural overhead without rasterising the image.

Private processing

SVG source is inspected and processed inside the current browser tab, not sent to an ImageOptimise image-processing server.

Vector format preserved

The output remains SVG, so shapes can stay sharp at different display sizes.

Safety-aware validation

Scripts, event handlers, external resource links and other active elements are removed or rejected before preview.

Batch ZIP download

Optimise one SVG or a batch of up to 25 and collect every completed result in one ZIP.

How to compress an image

From original image to lighter file in three steps

No account, installation or compression expertise is required.

01

Add SVG files

Drop vector files into the tool or browse your device. Every file is checked before a preview is created.

02

Validate and optimise

The browser removes unsafe active content and unnecessary structural overhead while preserving safe vector artwork.

03

Review and download

See the honest output size, then download one SVG or every completed result in a single ZIP.

Understand SVG optimisation

SVG is vector markup, not a raster photograph

The SVG pipeline preserves the vector format. It does not apply JPEG-style quality reduction and does not pretend that a complex illustration can always shrink dramatically.

SVG

Structure-aware

Safe markup is serialised more efficiently while comments, editor metadata and avoidable spacing are removed.

Safety-aware

Executable elements, event attributes and unsafe external references are removed before the file is previewed or downloaded.

Vector preserved

Paths, shapes, gradients and text remain vector content rather than being flattened into a fixed-size bitmap.

Honest SVG results

Safe structure matters more than an impressive percentage

SVG savings depend on how the file was exported. A design application may add comments, metadata and formatting that can be removed safely, while a carefully prepared icon may already be compact.

If a valid SVG cannot be made smaller without changing its safe artwork, ImageOptimise retains the original. If unsafe active content is found, the downloadable result is the cleaned SVG even when that safety correction does not reduce the byte count.

Always review important brand artwork before replacing a master source file, especially when it was exported by a specialist design application.
Current optimiser safeguards

The output remains SVG.

The viewBox and intended dimensions are preserved.

Active scripts and unsafe external references are not retained.

No raster quality setting is applied.

Common uses

Optimise SVG logos, icons and vector illustrations

Use the SVG optimizer for scalable website marks, interface icons, diagrams and lightweight illustrations where vector sharpness matters.

Websites and blogs

Prepare hero images, article photographs and interface graphics before uploading them to a CMS or landing page.

Online stores

Reduce product and category image weight before adding assets to an ecommerce catalogue.

Email and campaigns

Create lighter promotional graphics for campaign production, review and handover workflows.

Reports and presentations

Reduce the source weight of images before placing them into documents, slide decks or downloadable resources.

Portfolio and client delivery

Optimise a batch and provide the completed assets together in one convenient ZIP.

Storage and collaboration

Use smaller working copies where full original encoding weight is not required. Keep original master files separately when needed.

Browser-based privacy

Your current tab owns the temporary image batch

The optimisation code and codecs are delivered to your browser, then supported images are decoded and processed on your device. Image bytes, filenames and job data are not sent to an ImageOptimise image-processing server.

  • No account is required to use the compressor.
  • Each browser tab maintains its own independent temporary batch.
  • Different devices on the same network do not share image sessions.
  • Clear All removes the displayed batch; closing the tab ends the session.

Image compression questions

Frequently asked questions

Clear information about formats, privacy, output and batch limits.

Does the SVG optimizer convert vectors into pixels?

No. The output remains SVG. Use the image converter only when you intentionally need a JPG, PNG or WebP raster copy.

Are SVG files uploaded?

No image-processing upload endpoint is used. SVG validation and optimisation run inside the current browser tab.

How is unsafe SVG content handled?

Document types, entities and invalid SVG are rejected. Executable elements, event handlers and unsafe external resource references are removed before preview and download.

Why is my SVG only slightly smaller?

A compact, well-exported SVG may contain little removable overhead. ImageOptimise reports the real result instead of promising a universal reduction.

Are SVG dimensions changed?

No deliberate resize is performed. The existing width, height and viewBox are preserved; where width and height are omitted, the positive viewBox is used for safe browser preview dimensions.

Can I optimise several SVG files together?

Yes. Add up to 25 SVG files, each no larger than 25MB, and download results individually or in one ZIP.
